VOL. 3 ISSUE 7 PAGES: 72R.N.I. NO. MAHENG/2016/75492 February 2019 100www.tndindia.com

India will progressively adopt prepaid energy meters and the nationwide rollout is expected to take three years to complete.

Currently, there is a variety of energy meters deployed in India – conventional analog, conventional digital, prepaid and smart. The idea is to adopt prepaid meters universally.

Let us discuss some technicalities. A prepaid meter is a digital energy meter that has thefunction of “measurement” and “control”. This “control” aspect is what separates a prepaid meter from a conventional meter (analog or digital) that has only “measurement” capabilities. This “control” mechanism allows disconnection of electricity supply by the utility for whatever reason, including non-payment of dues.

With prepaid meters, an electricity consumer will pay in advance for future consumption. For a power utility, nothing could be better in terms of commercial efficiency. At the moment, most power discoms are facing negative cash flows because of widespread under-recoveries of dues. Prepaid metering can work towards correcting the commercial inefficiency of power utilities by ensuring positive cash flows.

Under Saubhagya, the national household electrification scheme, there has been a quantum jump in the number of electricity connections. Since its launch on October 11, 2017, some 2.47crore households have been electrified. With growing electrification, power utilities ironically face the prospects of more under-recoveries. Prepaid energy meters can help forestall this adversity. For the economically weak consumer, a prepaid meter helps manage electricity dues.

What about smart meters, which are assumed to be the quintessence of a Smart Grid? A smart meter has all the functionalities of a prepaid energy meter with the additional feature oftwo-way communication. Briefly speaking, both the utility and the consumer can understand electricity consumption much better, and take appropriate steps. For example, a consumer can plan his electricity usage using the “time of day” tariff feature and rationalize his electricity bills. On the other hand, a smart meter also allows the utility to temporarily disconnect supply of heavy consumers, with a view to flattening the peak load curve at that time.

An interesting landscape will emerge where all energy meters will be prepaid – but with varied degree of smartness. A typical rural household will have a rudimentary prepaid meter with basic measurement and control functionalities, while a Smart City meter, say, will be replete with sophisticated features. This is sensible; there is no point in saddling a rural consumer, with limited energy consumption, with a smart meter that is 70-80 per cent costlier than a basic prepaid meter.

A nationwide rollout will also mean achieving the economies of scale of mass procurement, through government agencies like say EESL. Prepaid meters can potentially create the same commercial efficiency that LED lamps did. A prepaid meter is indeed a smart step ahead.

Maharashtra StateElectricity Distribution Company Ltd

(MSEDCL) has appointed input-based distribution franchisees for two circles – Malegaon and Shil, Mumbra & Kalwa.

The Malegaon mandate has beenclinched by CESC Ltd, an RPG-Sanjiv Goenka company. In a stock exchange communication, CESC said that it has received a letter of intent from MSEDCL declaring it thesuccessful bidder for the MalegaonMunicipal Corporation area under the Malegaon circle.

In an independent announcement, Torrent Power said that it hasemerged winner as the input-based

distribution franchisee for the Shil, Mumbra & Kalwa sub-divisions under the Thane Urban Circle.

In both the cases, the tenure of the appointment will be 20 years.

The Shil, Mumbra & Kalwa sub-divisions have a consumer base of 2.15 lakh. In FY17, considered as the base year, the ATC losses for the given region were estimated at 47 per cent. The quantum of electricity supplied was 677 million kwh while net sales were only 376 million kwh.

Torrent Power’s obligations under the distribution franchisee agreement (DFA) will be to distribute electricity to the consumers on behalf of MSEDCL in accordance

with applicable law, regulations and directives of MERC. TPL is expected to upgrade the infrastructure, improve quality of supply and lower AT&C losses; whereas MSEDCL is obliged to supply input power atannual input rates as agreed under the DFA.

It may be mentioned that in January 2007, Torrent Power wasappointed DF for the loss-making Bhiwandi circle. This representedMaharashtra’s first experiment with private sector participation in the power distribution sector. Followingthe impressive turnaround staged by Torrent in Bhiwandi, the the ten-year contract was extended for another ten years, up to January 2027. �

Solar-based EV chargers on highwayBEST to extend 677-mw PPA with Tata Power

MAHARASHTRA Electricity Regulatory Commission (MERC) has allowed Brihanmumbai Electric Supply & Transport Undertaking(BEST) to extend its existing power purchase agreement with TataPower Company Ltd for 677 mw, supplied from its Trombay thermaland hydropower plants, for a period of five years — from 1 April2019 to 31 March 2024.

After the due diligence for ensuring the reliability of supply and costcompetitiveness for BEST consumers in Mumbai, MERC, in its order on January 2, 2019, approved the extension. The order came after BEST inter alia submitted that the cheapest option before BEST is theextension of its present PPA with Trombay thermal power station andhydropower plants of Tata Power. BEST and Tata Power have agreedfor an extension of PPA with existing terms and conditions

‘Tata Power is committed to supplying the most reliable andcompetitive power meeting the needs of BEST consumers, asalways,” said Praveer Sinha, CEO & Managing Director, Tata Power.

The process of power tie-up was undertaken by BEST in 2017-18for its discom consumers for the period of next five years starting1st April 2019. The existing power tie-up of 677 mw between BESTand Tata Power is scheduled to expire on March 31, 2019.

This will ensure cheaper power to Mumbai consumers with theadded advantage of hydropower peaking at rates that are cheapestin the country. This will also ensure continuity of reliable power supply to Mumbai consumers from embedded Tata Power thermaland hydropower generating stations in view of the transmissionconstraints.

What are LV cables typically tested for? Are there separate tests for conductivity and insulation?LV cables are typically tested for tests on conductor, tests on armouring wires/strips, tests for thickness of insulation and sheath, physical tests for insulation and outer sheath, insulation resistance test, high voltage (water immersion) test, high voltage test at room temperature and flammability test.

Tests on conductor comprises of annealing test (for copper), tensile test (for aluminum), wrapping test (for aluminum) and conductor resistance test.

Physical tests for insulation and outer sheath comprises of tensile strength and elongation at break, ageing in air oven, shrinkage test, hot deformation, loss of mass in air oven, heat shock test and thermal stability test.

LV cables are type tested as per IS694, IS1554-part-1, IS7098-part-1, IS9968-part-1 and other applicable

standards. It is also tested according to similar BS and IEC standards.

As you can see, there are separate tests applicable for conductor and Insulation of cable.

These days, a number of companies are offering fire-retardant cables of various types – fire survival, fire retardant, low smoke, etc. Please discuss the type-testing of such cables and tell us whether such testing falls under ERDA’s current scope?The behavior of cables in presence of fire or flames covers various aspects. One aspect is how the cable reacts in these circumstances. This brings us to consider two properties of the cables, which is being flame retardant and fire resistant.

Flame retardant cables can resist the spread of fire, but due to fire the cable is fully destroyed and no circuit integrity is assured. All the systems connected to cables are completely shut down. Flame retardant cables

Electrical Research Development Association (ERDA) is a professionally managed not-for-profit technical organisation serving industries and utilities for over 40 years in the areas of test, evaluation, certification, consultancy and R&D related to electrical products and systems. Hitesh Karandikar, who recently took over as Director, ERDA, in this exclusive interview, gives an in-depth understanding of ERDA’s capabilities in the field of testing cables and conductors. Developing facilities to test 400kV cables and HTLS conductors are going to be ERDA’s key contributions to the industry in the near future, notes Karandikar.

are not intended to assure service during a fire but are chosen to prevent the flames from spreading and causing further damage.

Fire resistant cables maintain circuit integrity and continue to work in the presence of fire. This property is important for fire alarm systems, emergency lighting and voice alarm systems.

In this case, it is possible to assure building evacuation, alarm signals, activation of extinguishing systems, etc. Fire resistant cables are always better than flame retardant cables as they assure the highest level of security during a fire.

The other aspect is gas emission and smoke density due to cables during fire. These are the quality and the quantity of gases that are evolved during the fire by the cables. In fact, the cause of fatalities to victims of fire doesn’t only consist of the presence of fire, but it’s also due to the gases that develop from the burning of materials.

The most popular material used for insulation and sheath for electrical cables is PVC (polyvinyl chloride). This material can show excellent flame retardant properties, due to the presence of chlorine in the compound, which is a flame suppressant. On the other hand,

chlorine is a corrosive and toxic gas and it develops heavy smoke. All of these characteristics have to be avoided in case of fire. This is why the following features have to be considered—absence of halogen (acid gas) in the cables and low emission of smoke.

Specific tests, according to different standards, are therefore defined to verify this performance.

ERDA has an NABL and ASTA accredited laboratory to carry out fire survival, fire retardant, low smoke zero halogen etc. as per IS,

BS, IEC and ASTM standards.

Tell us in brief about ERDA’s scope of activities in testing of conductors like Al, AA, ACSR, etc.ERDA has complete testing facility for type tests, acceptance tests, routine tests as well as special tests on various types of conductors in accordance with national and international standards as mentioned below:

Aluminum Conductors Galvanised • steel reinforced (ACSR) -- as per IS: 398 Pt. 2 and Pt. 5, IEC 1089, BS: 215 Pt. 1 & 2.Aluminum Stranded Conductors • (AA) -- as per IS: 398 (Pt. 1) All Aluminum Alloy Stranded • Conductor (AAAC) -- as per IS: 398 Pt.4 & IEC 1089ERDA also has complete type

testing facilities for T&D hardware and the unique facility for evaluation of vibration dampers as per IS: 9708

ERDA is in process of setting-up test facilities for Optical Ground Wire (OPGW) as per IEEE 1138 and High Temperature Low Sag (HTLS) conductors.

India is beginning to see increased usage of EHV cables (above 220kV). How is ERDA equipped to test the same?At present, ERDA is well equipped for testing of EHV cables up to 220kV rating. ERDA has established 600kV EHV partial discharge laboratory which can test all products up to 245kV voltage class. Also the impulse facility is equipped with 1600kVp and short-time current withstand test facility up to 120 kA /1 sec is available at ERDA.

ERDA is also planning to enhance this test facility for 400kV class cables shortly.

When it comes to testing of cables and conductors, are there any tests for which Indian manufacturers need to avail the services of foreign labs? Please discuss.It is not required to send cable sample outside India as ERDA is

well equipped as per IS/IEC/BS/ASTM/customer/manufacturer ’s testing requirement.

However presently testing facilities in the country are not available for OPGW and HTLS conductors. Manufacturers are forced to go to foreign laboratories for conducting test on these conductors. However, testing facility for OPGW and HTLS conductors are under construction at ERDA Vadodara and are expected to be operational by end of this year. After completion of HTLS conductor testing facility, ERDA will be the first laboratory in India to have comprehensive HTLS conductor testing facility.

Converserly, does ERDA help

meet the testing requirement of cables and conductors of overseas manufacturers?

Yes, foreign manufacturers mainly come to ERDA for developmental testing, routine testing, acceptance testing and testing on fire survival, fire retardant, low smoke zero halogen properties.

ERDA is directly approved by ADWEA (Abu Dhabi), TNB (Malaysia), DCRP (Oman) and DEWA (Dubai). ERDA is also an Intertek, UK accredited laboratory for ASTA certification.

Various foreign manufacturers and end users from Oman, Dubai, Abu Dhabi, Sharjah, Sri Lanka,

Singapore, China, etc. have availed services of ERDA for testing of cable or cable components.

ERDA’s cost effective but international quality testing services encourages these foreign manufacturers and end users to avail cable testing services from ERDA.

In field of testing and certification of cables and conductors, please discuss how ERDA plans to enhance the scope of its services, in the medium term.

Recently, ERDA developed Partial Discharge test laboratory to cover complete type test facility of HT cable up to 245kV. ERDA also offers its services to conduct developmental test on various cables. ERDA is ready to offer testing services by testing cable samples and providing test results with minimum possible time.

As discussed, testing facilities for OPGW and HTLS conductors are under construction at ERDA Vadodara and are expected to be operational by end of this year. After completion of HTLS conductor testing facility, ERDA will be the first laboratory in India to have comprehensive HTLS conductor testing facility.

ERDA is always upgrading its facilities to meet the exacting needs of Indian cable and conductor manufacturing industries and utilities, who use a wide range of cables and aerial bunched cables. �

Tell us how Schneider Electric, with two leading brands Modicon and Invensys under its fold, has evolved as a leading player in the industrial automation space.The advent of Modicon brought the first level of basic automation in the manufacturing sector. We are the first company to introduce PLC (programmable logic controller) to the industry, which was fifty years ago. Modicon removed the cumbersome “physical layers” from the manufacturing industry. Everything then was hard-wired. If you needed to customize your products, you needed to bring about multiple changes in the manufacturing process. Modicon, in fact, facilitated the entry of

companies in the manufacturing sector. Modicon has been in India, right since its inception.

Modicon has helped the manufacturing industry, especially the process industry, to reduce manufacturing costs, improve efficiency, etc. We acquired Modicon and ventured into the space of high-end automation for the continuous process industries.

When we speak of continuous process industries (e.g. oil and gas), Invensys comes more into the picture.

When there are applications that are hybrid as well as discreet (e.g. metals, pharmaceuticals, paper, food processing, etc), we see Modicon playing a bigger role.

Schneider Electric completes 50 years of its first programmable logic controller (PLC) Modicon this year. On this occasion, Meenu Singhal who heads the industry business in India, tells Venugopal Pillai about how Modicon, and the relatively newer acquisition of Invensys, has helped Schneider Electric to penetrate deep into the factory automation business. Singhal also explains how Schneider Electric, with its automation solutions, can take the Indian manufacturing sector closer to “Industry 4.0”.

We can help make manufacturing more globally competitive

Schwenk, and Jonas Landau (pictured from left to right).

FACE-TO-FACE


Thus, the combination of Modicon and Invensys give us the edge and places us well above our competition.

How will Schneider Electric support Industry 4.0?Schneider Electric is an energy management company, and the industrial automation business is very much aligned to all the businesses that the company is in. Aligning the company’s core values to the national “Make in India” goal is where we are playing a big role. In Industry 4.0, every manufacturing process requires the adaption of smart technologies and digital transformation.

If you look at the manufacturing value chain – right from raw material to finished goods production (physical) and from the cyber security to the supply chain (digital), there is need to get connected to collect data.

A critical aspect of Industry 4.0 is “Analyse”. Using augmented reality and artificial intelligence, we strive to derive the best for the manufacturing

process. All kinds of manufacturing sectors are very well driven by “Make in India” and also “India for India.” Our automation solutions can help the manufacturing sector produce goods that are compliant with all regulations, so that they also have an exports market.

Which segment of the manufacturing sector is most receptive to adopting industrial automation solutions?As such, everyone. However, the multinationals that are present in India are the fastest adopters of industrial automation solutions. They need to produce the same standard of products globally. Even government-owned companies in the manufacturing sector are investing heavily in Internet of Things (IoT) and industrial automation, to ensure that inefficiencies are curbed. We have been able to make manufacturing plants 20 per cent more efficient just by optimizing the existing assets, which is without investing in new assets. This is our philosophy of “doing more with less.”

Small and medium-sized players want to be globally competitive. They also want to establish that their goods are comparable with imported ones, without compromising on quality. I don’t see the dearth of acceptance of “Industry 4.0” from any segment of the industry. The levels might be different – in terms of goods produced, workforce employed, etc.

For instance, a biscuit manufacturer needs to sell his products for a fixed price although his costs are going up. For this, he needs to change the size of the biscuits (reduce it) and also change the packaging. If the manufacturing and packaging process is manual, this change could take ages. However, with an industrial automation solution like Modicon, such customization is easily possible. Such customizations are also fast. It is possible to create new formats in a matter of hours or even minutes.

How do you deal with manufacturing setups where there is already some level of automation? Are there legacy issues?When we talk about legacy industries and they have basic level automation already with them, we need to have products that can talk on an open platform. Modicon created Modbus that was the first open platform for communication. We don’t care who is at the bottom. If there are connected devices sitting at the bottom, it is easy to connect with them without any significant additional investment. May be, a few wired I/O modules need to be changed.

In case there mechanical processes running without connectivity today, do we need to revamp the entire system? The answer is no. There are transmitters, flow meters and other instrumentations that can be retrofitted. These need some “surgical” operations to be embedded into the process machinery, for example in pipelines, etc. When this instrumentation is in place, it gets

FACE-TO-FACEconnected to the top-end devices for analytics. In this way, without major investment, one can replace manual data collection (for example, measuring temperature, pressure, etc) by an automated system. When data collection is automated, it is real time and of course the chances of slackness from manual intervention are eliminated. After all, real time data is where the entire industry around Big Data has surfaced.

The message to the industry is: “Start from where you are, we have opportunities and options to work with you.”

Tell us about automation in the power sector, across the value chain.I would like to say that in the power value chain, we have solutions from raw material handling for power generation plants right up to operations and maintenance in the power transmission and distribution (T&D) sector. In coal-fired plants for instance, boiler control is a major area where we are present. We have SCADA connectivity even in the renewable energy sector like solar and wind. In the power T&D chain, the critical aspect is maintenance. In case there are faults happening, how quickly can one pinpoint the snag and take remedial action. This is called “fault localization” and has become very quick, thanks to automation and IoT. Testing and fault correction has become very fast today when compared with conventional methods of the past.

How do you see the market ahead?We are very optimistic and bullish about the growth in the industrial automation market. If I can recall some of the data and figures that I have, we are expecting this market to reach $3.5 billion by 2020, only in India. Not only this, we are also expecting this growth to fuel up new jobs to the tune of 90-100 million by 2020, in India. We feel that this is a booming market. The Indian manufacturing sector is currently

not running on its optimum capacity and efficiency. More and more people are now understanding that they need to “do more with less” to stay competitive. This has resulted in growth of investment in industrial automation, both for greenfield and retrofit applications.

Industrial automation, as you see, will be a growing sector and will also create jobs. What is your view on skilling the workforce required in this field?We do have our own training programmes, some also done in collaboration with government and private institutes. We have already trained lakhs of electricians and technicians already; it also an integral part of our CSR mission. We want industrial automation technology to be widely adapted and there should be sufficient number of people locally available to service and support. For this, there is no option but to train more and more people. We have our partners, our distributors and our solution

providers who have their workforce. We continuously train and upgrade this workforce. We also train third-party works, which are electricians. Training is one thing that we are already investing in and we will continue to do so.

I would also like to mention here that the composition of the workforce over the next few years is going to change. As it happened during the IT revolution, there will be a transition of jobs from “physical” to “digital”. We will need a lot of workforce for digitally oriented jobs like development applications (apps), programming, analytics, etc. Of course, there will be a rung of the workforce that will typically include operators.

Schneider has a complete portfolio of services in the LV/ MV electrical domain. How does industrial automation complement this? How can Schneider Electric therefore offer a complete bouquet of services to a manufacturing unit? We start from the basic need of the manufacturer. Suppose there is a new plant coming in. The plant owner has land and a sanction for electricity; everything else has to be created. We, at Schneider Electric, want to be the one-source single supplier that can cater to the complete needs – right from the power connection to automation of the manufacturing unit. We ensure that the plant owner is able to manage energy very effectively. We also ensure there are no disturbances (e.g. harmonics) that can adversely affect energy consumption.

We will give you energy saving techniques, improve efficiencies, maintain quality of power. We ensure that manufacturing units maintain IEC standards. We also take care of the reliability and safety of the power systems. For this, we are associated with the plant owners, right from the beginning. This is the essence of a smart factory where everything is measurable, controllable and communicable. �

We are enthusiastic to map out the actions plan so that India could be, in the next 7 years, in the top 10 countries of Prysmian’s sales turnover.

India today consumes 8 per cent of the worldwide energy. The needs increase sharply and the energy mix will change widely in the future. Thanks to the strong will and effort of the government, $10 billion have been spent so far in the renewable energies, reducing emissions and mitigating climate change.

A strong impetus has been placed on solar and wind farms will, thanks to government incentives, namely the creation of the International Solar Alliance (ISA). Already 62 GW are currently in use, it will increase to 175 GW within 2022, out of which 100 GW in solar, 60 GW in wind, 10

in biomass and 5 GW in hydropower. We acknowledge India’s strong motto ‘’ One World, One Sun, One Grid ‘’ that embodies in an efficient and effective energy transition.

Innovation: In all these areas, Prysmian proposes innovative cable solutions, thanks to a longstanding track record of offering our customers proven cost-effective cable designs. Prysmian listens and work closely with the key accounts, and is a trusted partner to the growing

industries, offering HVAC, HVDC cables, or turnkey solutions.

Prysmian group constant drive for innovation is a daily philosophy at the group level, to provide top quality cables. For example, array cables of 66kV instead of 33kV, with EPR insulation transport more power, reduces the cable length, and consequently the total investments—increasing our client’s productivity.

The constant drive to research and use of innovative materials include the environment criteria. For example, P-Laser is an eco-friendly cable, with higher performance

than XLPE, using HPTE (High Performance Thermoplastic Elastomer Polypropylene)-based insulation. P-Laser insulated cables withstand increased operating temperatures by over 20 per cent., abiding to fluctuating demands in harsh environments. P-Laser production process utilizes zero gas technology reducing CO2 emissions by 1 tonne per km; even degassing is no more required.

Another innovation example is the use of Prycam standalone or on-cloud Prycam devices to measure partial discharge, without service interruption. It eases the assets management, helps the prevention maintenance strategies and allows savings for utilities. It reduces maintenance costs, and matches the smart cities requirements.

We are also working on ultra high voltage DC systems aiming to develop an 800kV extruded solution, always keeping in mind sustainable solutions, to reduce

power dissipation, or power losses. Prysmian group engaged in

partnership and R&D scientists to use nanotechnologies in power, control and instrumentation application, improving mechanical resistance, low weight, chemical inertness, high degree of flexibility, electrical and heat conductivity.

All these initiatives allow Prysmian to propose dedicated, innovative and complete solutions for select markets. �

THE CUSTOMER’S CHALLENGE

Distribution transformers are a key part of your low-voltage distribution

networks. If a transformer overheats and fails, it can be devastating to the utility. A widespread outage might disrupt power to thousands of customers, and the cost to repair or replace equipment is expensive. An overheating transformer might be evidence of an improper machinery condition, progressive deterioration of the electrical isolation or machinery elements, or bad operating parameters, such as current, voltage, and temperature. With so many possible sources of the problem, it can be difficult to pinpoint the exact cause.

A SOLUTIONTemperature is a key element in ensuring the working status of distribution transformers. Regular temperature monitoring using advanced diagnostic thermal imaging cameras can help you catch impending failures before they occur. By using FLIR handheld thermal cameras, you can easily inspect and monitor the temperature distribution on the outside surface of each transformer. It will show you what the naked eye can’t see – hot spots that indicate overheating parts

– so you know where to investigate further. The high-performance FLIR T660 is an ideal solution to help you find hidden signs of electrical resistance and mechanical wear, so you can begin repairs immediately. The FLIR T660 features options with a 24° or 45° lens, which will give you a larger field of view when you

have limited space in front of your transformers. This thermal camera can measure temperatures up to 2000°C (3632°F), and it provides 640 x 480 thermal resolution for superior image quality and clarity.

THE RESULTSRepairing or replacing a transformer is expensive. A thermal camera pays

for itself when you consider the money saved by having the ability to fix a problem before it results in a shutdown. Through regular thermal inspections, you can rapidly detect and locate overheating areas on the surface of a transformer or hot spots on electrical connections. Once you determine that something is overheating you can investigate further, such as with ultrasonic, vibration, or oil analysis. The benefits of catching hot spots early include extending the life of otherwise well-functioning equipment; prevention of equipment failures that could lead to widespread outages, reduction of costs through maintenance as opposed to replacement of damaged equipment, and improved safety by reducing the risk of fires or explosions that may result from transformer failures.

Please orient us with your Sanchore manufacturing facility in Rajasthan. What are the various transformers that you produce and what is your indicative annual capacity?An ISO 9001, 14001 & 18001 certified company established in 2010 with in-house facility to produce transformer for diversified application, our manufacturing facility is spread over 8 acres of land and employs 140+ professionals. The state-of-the-art facility has latest machinery that are second to none in the industry. We are equipped to produce various ratings of transformer ranging from 10kVA to 8000kVA with highest voltage class of 33kV. Our products comply with international standards like IEC, IEEE, etc.

We understand that RPTPL also has in-house testing facilities for transformers. Tell us more.For confirming the performances of

transformer as per specification, it has to go through routine tests. All routine tests are carried out on each transformer as per IS2026 and every instrument is calibrated through NABL accredited laboratory. Heat run test is also carried out in factory premises.

Given the boost in demand for distribution transformers coming from Central schemes like DDUGVY, Saubhagya, etc, are you planning any capacity expansion at the Sanchore unit?Eight years back, while venturing in this industry, our aim was to create a unit which could cater to our expansion vision for the next 10-15 years. Hence there seems to be no need for a capacity expansion at this moment. However, I must say that as and when there is any technological development, we immediately adopt it.

Established in 2010, Rajasthan Powergen Transformer Pvt Ltd is a young enterprise that has witnessed significant growth in a brief period of time. RPTPL, through its modern facility in Rajasthan, caters to both the Indian and foreign markets. In this interview, we have Arvind S. Jain discussing his company’s current operations and future plans. While dwelling upon industry issues, Jain strongly feels that state power utilities should have uniform transformer designs—a move than can bring in tremendous cost and time efficiency.

INTERVIEW


Speaking of industry issues, it is believed that India has the highest failure rate of distribution transformers. What is your view? There are various internal and external reasons that can initiate transformer failure. Poor workmanship cannot be a major reason as all varieties are type-tested and also 100 per cent inspection is done by utilities before dispatch. Many factors like line surges, electrical disturbances, overloading and sometimes even sabotage, impact the life expectancy of the transformer. So, it is not always a manufacturing issue but the external issues that degrade the capacity of the transformer to withstand the daily stress.

We understand that distribution transformers manufacturers have to get dual certification from BEE and BIS. What is your opinion? Broadly speaking, this is a voluntary depletion of resources. Dual certification, adding to the fact that every state utility has a different specification, consumes a lot of time, energy and cost. It is sometimes not practically possible to reach out to various states due to additional tests. Initiating a policy like “One India, One Product” makes sense in reducing these hassles as well as conserving vital resources. And

a direct benefit can be made as it would trigger a healthy competition throughout the country.

What is your overall view on the alleged use of non-prime grade CRGO in India, especially in the case of distribution transformers?Utilities should use effective procurement policies based on standard quality procurement, not on the L1 mechanism. Estimated cost decided by procurement entity should be based on healthy design of transformer as low cost ultimately directs to use of unhealthy design, substandard materials, leading in to increase in electrical losses. Thus, alleged use of non-prime grade CRGO and unhealthy design adversely affecting the quality and disturbing the standard industrial practices.

Do you feel that Indian testing laboratories (CPRI, ERDA, NHPTL, etc) have adequate capability and capacity to cater to the Indian demand for testing high-voltage equipment? Not really. Understanding Indian demand for next 10 years and the way India is progressing, its testing capacity should be enhanced. There should also be more branches of testing labs so as to cut down waiting time, which sometimes is as high as three months. Further, KEMA type of facilities should be introduced so that our type-tested products are acceptable globally.

We understand that most utilities still use the L1 mode of procurement. This, as we understand, causes sub-standard equipment to be inducted into the grid. What is your overall view on this subject?Highlighting the same point made earlier, till utilities do not have in-house design and evaluation process of minimum cost of any product, following L1 model might give onetime benefit but will reduce the life of system and also add pressure on system. System losses would be proportionately more, which in turn will increase tariff burden. Ultimately, the consumer will always carry this burden. This is a vicious cycle.

Does RPTPL cater to the exports market? If so, which countries are your prime export destinations? Yes, we are presently exporting in Africa and more actively looking forward to cater to the requirement of Middle East and other ASEAN countries.

Please summarize your growth plans for RPTPL for the next say 5-7 years. Looking at India’s overall plan of infrastructure development we see good potential in Indian market. At the same time, developing countries like Bangladesh, Nepal and African countries are also showing promise. So, being optimistic and maintaining consistent growth for RPTPL, we expect an annual sales turnover of Rs.250-300 crore in the coming years. �

Maharashtra, which has the credit of appointing the country’s first private distribution franchisee (DF)

way back in 2007, had some reasons to cheer. After a long passage of time, the state concluded two more DF agreements. In the first week of January 2019, state power utility Maharashtra State Electricity Distribution Company Ltd (MSEDCL) appointed input-based distribution franchisees for two circles – Malegaon and Shil, Mumbra & Kalwa.

The Malegaon mandate was won by CESC Ltd, an RP-Sanjiv Goenka company. In a communication, CESC said that it received a letter of intent from MSEDCL declaring it the successful bidder for the Malegaon Municipal Corporation area under the Malegaon circle. The second instance was that of Torrent Power, winning the input-based distribution franchisee mandate for the Shil, Mumbra &

Kalwa sub-divisions under the Thane Urban Circle.

For Maharashtra, the finalizing of these two mandates is a morale booster given that the bidding process for these two circles faced delays due to repeated iterations in the invitation of requests for proposals. It is also encouraging to note that Torrent Power that had won the 10-year DF mandate for the Bhiwandi circle in 2007 saw its mandate being extended for a similar period, now up to 2027. It is widely believed that Torrent Power’s appointment as DF for the then loss-making Bhiwandi circle represents India’s first experiment in privatization of power distribution under the DF route.

The years 2016 and 2017 were very propitious for the DF environment with four mandates being finalized, incidentally all in Rajasthan. While CESC won the mandates for the Kota and Bharatpur circles in July 2016, the utility clinched Bikaner in March 2017.

Note: List may not be exhaustive

Shortly thereafter, Tata Power landed the DF mandate for the Ajmer circle. For both CESC and Tata Power, longstanding distribution licencees, these mandates represented their entry in the distribution franchisee space.

According to information compiled by T&D India, there are eleven DF mandates in force, as shown in Table 1. What is disconcerting is that DF agreements have been rescinded in alarming number. Statistics available with T&D India are suggestive of the fact that at least nine DF mandates have been cancelled, after appointment of the franchisee. This does not include the significant number of DF appointment attempts that never came to fruition.

Maharashtra has had trouble with three DF mandates. The agreement for the Aurangabad circle that was handed over to Global Telesystems Ltd (GTL) in May 2011 was officially revoked in November 2014. Similarly, the Jalgaon circle that was entrusted to Crompton Greaves (CG) in November 2011 was reclaimed by MSEDCL, the state power distribution utility, in August 2015. The Nagpur franchise, comprising divisions of Civil Lines, Gandhibag and Mahal of the Nagpur Urban circle, was handed over to private franchisee Spanco,

an IT-centric company, in May 2011. The circle was subsequently acquired by Essel Group, which has since managed to stage a turnaround.

In a recent interaction with T&D India on the subject, Arvind Singh, Principal Energy Secretary, Government of Maharashtra, had observed: “Companies with no experience in the power sector were allowed to get in. These were mainly IT companies who got in and thought they could manage the business by hiring people with power sector experience, but they were unable to do it.”

Essel Utilities, which today is the distribution franchisee for two circles – Nagpur (Maharashtra) and Muzaffarpur (Bihar) – had to contend with its mandate revoked for as many as three circles in Madhya Pradesh – Ujjain, Sagar and Gwalior. In Ujjain and Sagar, the private DF had run operations for a year and had even halved the ATC losses from the then-ruling 45 per cent. However, consumers were unwilling to pay electricity bills and the mandate was cancelled due to several factors, including political pressure. In an interview with T&D India, Brajesh Singh Bhadauria, CEO, Essel Utilities, observed: “When a private player enters this (DF) business, it endeavors to reduce power theft. It works towards reducing distribution losses. This undoubtedly pushes consumers to pay bills. So when we took over the operations and began putting in a mechanism to streamlines things, we faced a lot a resistance from all quarters. The matter also gets embroiled in politics.”

Established players like Torrent Power, Tata Power and CESC also suffered loss of DF mandates. While Torrent had to relinquish the Kanpur circle in Uttar Pradesh, Tata Power lost its rights over the Jamshedpur

circle in Jharkhand while CESC lost the Ranchi mandate, also in Jharkhand. In almost all these cases, the private operators had taken over the business and had even brought down ATC losses. Revoking of DF mandates was the result of pressure from various quarters, including political. SPML Infra, too, saw its DF mandate in Bhagalpur (Bihar) getting terminated abruptly.

WAY FORWARDThere are several urban centres where ATC losses are unacceptably high. Add to this the fact that there has been a stupendous increase in the number of household electricity connections under the Saubhagya scheme. According to government statistics, some 2.40 crore households have been issued an electricity connection from between October 11, 2017 (the launch date of Saubhagya) and December 31, 2018. With such massive electrification taking place, the next logical move would be to ensure commercial viability of the new connections. Privatization of loss-making circles, under the DF model, assumes significance on this count.

Clearly, the DF model has not gained much acceptability amongst private players. Going forward, it is likely that only reputed distribution licencees, of the likes of Tata Power, Torrent Power, CESC, Adani Power, Essel Utilities, etc, would be the ones showing interest in future rounds of privatization.

All said, even state-owned discoms must ensure that there is enough handholding given to the incumbent private DF. Consumers must be sensitized to the fact that electricity is not “free lunch” but a commodity that needs to be paid for. A distribution franchisee is essentially appointed to improve commercial efficiency. A DF would obviously work towards improving collections and recoveries. In doing so, there is bound to be some social resistance. But this resistance can be overcome by sensitizing consumers to the commercial aspects of electricity. Unfortunately, this social resistance, in many cases, is quickly transmuted into a political issue and a “populist measure” is adopted, which unfortunately is that of terminating the contract of the distribution franchisee. For decades on end, promises of free water and free electricity have been the two most important election planks. There are legacy issues related to electricity, especially when it comes to payment. This situation will change but only with the passage of time. �

PROFILEPROFILE

In linking computing units to data centers, modular connectors in the Han-Eco® Modular plastic

housing have proved their worth as a standard solution for the fast and cost-efficient design of the power supply.

When it comes to supplying data centre computing units with power and data, and networking devices with as little effort as possible, from an operator’s point of view there are two things that are key to successful operation:

The computing units must be • installed quickly and therefore in a cost-optimised mannerComputing capacity losses • resulting from faulty computers need to be able to be resolved quickly and smoothly so that the available capacity and/or memory remain as large as possible and no data loss results In view of these requirements,

the structure of modern data centres is highly standardised. Mutually harmonised, ready-made solutions for architecture, infrastructure and computing units are the rule. The demand for prefabricated units in total installed computing capacity is constantly on the rise. Data

centre developers have responded to challenges by employing a high degree of modularity – without losing sight of the overarching goal of optimal installation. It is important to install as much computing capacity as possible, with the infrastructure around the storage units being required to meet the same requirements. In many projects, there is a three-stage power and distribution level for the uninterruptible power supply.

In the system, which is built like a family tree, the maximum currents to be transmitted are 100A, 70A and finally 40A at the lowest distribution level. Up to 20 units are suspended at each end of a tree – in addition to memory, there are also e.g. fans, in order to reduce heat. Data centre

planners are faced with the question of how to tie together and connect the different levels of power distribution as quickly as possible. The means of choice has often been hardwired prefabricated units in the field, not only in North America, where the largest data centres are.

This method places high demands on the expertise of personnel in the field and also prevents a smooth build-up of systems at the installation site. As with many infrastructure-based requirements for connection technology, the HARTING Technology Group has also implemented just the right solution here for users, and has used this approach in numerous projects with the Han-Eco® plastic connector together with well-known storage operators. Han-Eco® series connectors win points above all thanks to their low weight, good handling and extremely robust design – factors which are absolutely essential for use on construction sites. As a contact insert, the Han Modular® system offers an extremely flexible option for power, signal and data transmission that meets all the specific requirements of the user. Not only do the required 40A, 70A or 100A current carrying capacities present no problem, the customer can also select different connection types and housing shapes.

In addition to connection technology, many of our customers also have the option of purchasing entire cable assemblies from HARTING. The end-to-end tested and optionally coded cables optimise the build-out of IT infrastructure and also reduce the risk of incorrect wiring to zero.

Thus, in the event of malfunction, faults in the cabling can largely be ruled out, and individual memory elements can be exchanged quickly without special knowledge. �

We understand that type-testing of low-voltage cables is done by DNV GL through its KEMA Laboratories. Please discuss.KEMA Laboratories has been testing all types of cables since the early 1930s. For low voltage cables, the main insulation used historically is PVCbut XLPE as insulation is becoming popular,as well as other materials for special cable applications. For medium and high voltage cable, mass impregnated oil filled cables have been used till the 1980s. This changed rapidly to XLPE insulation due to the excellent dielectric properties of XLPE. KEMA tests and certifies low, medium and high voltage cables in our KEMA Laboratory located in Arnhem – The Netherlands. In parallel, KEMA witnesses type testing at laboratories from manufacturers. KEMA does

not issue KEMA Certificates based on inspection but issues inspection or test reports.What are the current international standards to which these tests conform?The following table shows an overview of the commonly used standards for LV cables. An interesting observation is that this includes IEC and BS standards. For medium and high voltage cables, IEC standards (IEC 60502, IEC 60840 and IEC 62067) are the most widely used standards.

DNV GL, a global quality assurance and risk management company, has extensive experience of type testing cables and accessories. Its KEMA Type Test Certificates are recognized around the world as a hallmark of quality. In this exchange, we have Bas Verhoeven expounding on the capabilities of DNV GL in the field of cable testing. Recognizing the growing demand in India, KEMA Laboratories has set up a new inspection service for the witnessing of cable testing in India. This move will bring DNV GL closer to the Indian market, feels Verhoeven.

Which countries are currently availing LV cable testing facilities of DNV GL? Does India feature in the list?The use of low, medium and high voltage cables goes hand in hand with the ongoing electrification of India and the growth of energy consumption. Like many other countries in the world, India is a vibrant market for all types of cables and especially for low voltage cables. KEMA Laboratories has been testing and certifying cables for Indian cable manufacturers and the KEMA Type Test Certificate is recognized as an important document to independently prove the quality of the cable to utilities and contractors in India, as well as for exporting a cable to other parts of the world.

Do you feel India is a potentially vibrant market for LV cable type-testing? If so, how is DNV GL addressing this key market?To improve our service to the Indian market, KEMA Laboratories has set up a new inspection service for the witnessing of cable testing in India. With this new service, we offer local inspections while having the reach of strong cable testing expertise from our experts in our main test laboratory in The Netherlands. We support the Indian cable industry with independent witnessing of type testing and factory acceptance testing (FAT).

EHV cables are gaining prominence worldwide, including India, for power distribution in urban areas as well as offshore wind farms. Tell us about DNV GL’s capabilities in the field of EHV cable testing.KEMA Laboratories is specialized in the type testing of low, medium and high voltage cable systems. Our experts are highly experienced in the testing of all kinds of cables, cable accessories and in all voltage classes both for AC and DC. For high voltage cable systems, we provide type testing and prequalification testing as per the relevant IEC

standards (IEC 60502, 60840 and 62067). Our customers are all main cable manufacturers from Europe, Middle East and Far East. Cable manufacturers from India are testing at KEMA because the KEMA Certificate is a trade passport that enables Indian manufacturers to sell cables in the Indian and international market.

Cables to connect onshore and offshore windfarms to the power network have special properties to meet the very high reliability demands of those connections. This requires special tests that can be executed at the KEMA Laboratories. For very special tests our inspection services are available to complete the full test program.

We learn that DNV GL also performs ageing testing on cables, based on simulation methods. Tell us more.Ageing tests are an integral part of the test program for low voltage cables. An energized cable is submerged in a water tank for a long time and the cable should not show any electrical break down. Comparable ageing tests are available for medium voltage cable to detect any negative ‘water treeing’ effects. The test duration is 1 or 2 years which is very long. KEMA laboratories developed and offers the accelerated method to ‘age’ the cable using a 500Hz voltage source which reduces the ageing time to just a few months.

Please summarize your outlook of the Indian market with respect to cable testing services.The Indian cable market is a fast-growing one in which many cable manufacturers act and where many newcomers are to be expected. Heavy price competition is expected, especially in the field of low and medium voltage cables. We all know that quality comes at a certain cost. Hence, it is important that all cables meet the standard minimum requirements that can only be checked by independent testing or witnessing. �

Siemens has been awarded an order to connect the Moray East offshore wind farm to the grid. Moray East is

being developed by a joint venture company owned by EDP Renewables, a subsidiary of the Portuguese utility Energias de Portugal, ENGIE, a global energy and services group based in Paris, and Diamond Generation Europe Ltd., a subsidiary of Mitsubishi Corporation. The Siemens’ scope of supply covers all necessary components, such as the offshore transformer modules (OTM®) which transform the output of the wind turbines from 66kV to the transmission voltage of 220kV, as well as the onshore station which transforms the electricity into 275kV for feeding it into the national transmission grid. This project will be the 11th offshore wind farm to be connected to the mainland by Siemens in the UK. Moreover, Moray East marks the largest offshore grid connection in terms of transmission capacity and order entry Siemens has delivered or been awarded in the UK to date.

The windfarm, 22 km off the Aberdeenshire coast in Scotland, will have an installed generation capacity of 950 mw after its completion. For the grid connection, Moray East will incorporate Siemens OTM®. As a world’s first, three OTM® are linked together to cover the rated capacity of 950 mw of the Moray East wind farm. As an OTM® is significantly smaller in size and weight compared to conventional alternating current platforms, there’s no need for special vessels for transport and installation. Thus, this innovation will save time and money and highlights Siemens’ commitment to helping power developers improve efficiencies and the delivery program.

Siemens will be responsible for the complete onshore substation including three SVC Plus as well as the three offshore substation platform topsides. In addition, it will also install a 30 km underground export cable to the onshore substation at New Deer in Aberdeenshire for the power generated. Work began on site in September 2018 to prepare the location which will house the

onshore substation. It is anticipated Moray East will be operational by April 2021.

Moray East represents a step-change in the delivery of renewable power in terms of cost and scale. The project will provide an abundant supply of low-carbon electricity at a highly competitive price: “The 950 MW offshore windfarm will generate power at £57.50/MWhr which is less than half the price of power generated by offshore windfarms under construction today”, said Ralf Christian, CEO at Siemens’ Energy Management Division. “The grid connection is one lever that can help driving down costs.”

Mirko Düsel, CEO Transmission Solutions at Siemens Energy Management, said: “These platforms for large-scale renewable projects make me incredibly proud. Not only do they incorporate our engineering excellence on a massive scale, they showcase our commitment to renewables and clean energy generation. We are delighted our market-leading technology is being used on this project.”

Oscar Diaz, Project Director for Moray East, said: “This is a landmark moment for a landmark project, making renewable generation highly competitive. We are grateful to local stakeholders who continue to engage with us on a range of initiatives to enable the economic opportunities created by the project to be realized as we move to construction.”

Siemens is a global leader in offshore grid connection and has extensive experience in this area. To date around 7,000 MW of offshore wind power has been connected to the grid by Siemens; a further 3,900 MW is contracted. Moray East will be Siemens’ 11th offshore project in the UK and the 14th connected with alternating current (AC) technology globally.

This project also supports the local industry by providing supplies and services to Siemens. Local Scottish contractor, I&H Brown, has already been appointed to manage the site enabling work by Siemens. The project will be delivered from Siemens’ Manchester office and it is anticipated several further supply chain contracts will be available for UK supply chain companies, with details due to be announced in the coming months. �

India is a high-potential but price-sensitive market

Air compressors are used in almost every manufacturing and process industry.

Generally when the economy rises and investment in manufacturing increases, so does the business of compressors improve. Products like automotive vehicles, electronics, textiles and plastics are driven based on consumer confidence, and when there is more spending, the compressor market grows. However there are also industries like food and beverage and pharmaceuticals that are always steadily growing based on population and heath awareness. These industries are more stable when it comes to compressors purchasing.

India is the fastest growing large

economy and as such every major player in the compressor market wants to be active in India to capitalize on this growth. As such we now see in India that there is a growing trend in new manufacturers with a lot of new companies entering the market. These are often being imported as components and being assembled here in India. We see this as a rapidly moving sector of the market but one that is normally very fragmented, unorganized and grows only to around 50–60 unit sales a year. Major companies are focused more on sustainable solutions and serving customers all over India with organized sales and service teams as well as a well supported dealer network. Challenges: The major challenge

remains the price sensitivity of the Indian market. Global players are seeing that to be competitive in India they need to provide products that represent their brand promises of quality and reliability but at prices accepted in the market. There are companies that are willing to pay for the value of options that are normally associated with improved energy efficiency like variable speed drive compressors, permanent magnetic motors, cost effective adsorption dryers or even higher IE-rated motors.

Make in India is still being implemented in many companies and the main challenge to be overcome by a lot of International companies, is how to make their production facilities competitive in India and how to handle the extremely price sensitive Indian

Oil-filled air compressors as a compressor technology is presently

increasing in size. The growth is driven predominately by the increase in small to medium enterprises. Such compressors are often used in industries where air demand is small. SME’s represent about 45 per cent of India’s total manufacturing output and such enterprises have been growing at a pace of 10 per cent and through digitalization this is expected to increase in the coming years. Oil-filled air compressors are often the go-to choice for companies due to reliability and efficiency they can provide for these lower flows. �

market conditions. Many globalplayers are adopting their strategies to be competitive inIndia and the expected rise inforeign investment is still yetto be heavily seen across thecountry but signs are positive.

The other challengeremains like many traditionalengineering industries isto right level of graduatingstudents. A lot of investment inpromotional activities to attractthe right level of engineersis required and then a lot of training is required to developthem to the expected level.Atlas Copco, for instance, has astrong brand reputation and wecontinuously invest in trainingand still see the need to work closer with many institutes tofind the right talent and that whichis able to deliver the expected work class solutions that our customersdemand.

Outlook: The outlook for the air compressor market is bright at themoment and is expected to remain so whilst manufacturing and power

industries invest. More major projects in metals and cement are expected as the demand slowly begins to grow bigger than the supply. We see many companies continuing to invest in India and with that drive we will continue to partner with them to provide the most sustainable solutions.

It is difficult to predict as the present market size is not universally known or documented. Unlike many countries, in India there is no independent body that collects the market size. All the same, a best guess is that the present market size is around 12,000 to 17,000 units a year. With expected market growth it is estimated that the market will grow above 22,000 to 25,000 units a year by 2022. �

PROGNOSIS

India Ratings and Research (Ind-Ra) has maintained a stable-to-negative outlook on the power sector for FY20 despite

the agency’s anticipation of a healthy 6-7per cent growth in power demand and an improvement in all India coal-based PLFsto 62-63 per cent. The stable-to-negativeoutlook continues to reflect Ind-Ra’s expectation of a slower-than-expectedresolution of the stressed capacity, domestic coal availability challenges, and limited appetite of discoms to sign long-term power purchase agreements.

The draft CERC guidelines have come as a relief to generators. However, the overhang of the stressed capacity would continue to prevent fresh thermal capacity addition from the private sector. The renewablesector would continue to account for bulk of the incremental capacity addition in the coming years.

The transmission sector would continue

to see investments in view of the various schemes launched by the government aspart of its goal of ‘24x7 Power for All’.However, for a large number of discoms, the actual AT&C loss remains higher thanthe target set under the UDAY scheme,leading to lower-than-expected reduction in overall loss. Timely and adequate tariffhikes would remain essential for a reduction in overall losses.

Ind-Ra expects the coal-based thermalcapacity PLFs to improve further to around 63.5 per cent in FY20, driven by healthy electricity demand. However, the rise incoal-based capacity PLFs is contingentupon coal availability. Coal India increasedits output by 7.4 per cent in 9MFY19 (April2018 to December 2018); however, giventhe historical coal production growth rateof 4 per cent and a higher base, Ind-Rabelieves continued production growth rateof 7-8 per cent could be difficult to achieve

in FY20. This would result in increasedreliance on imported coal.

The pace of resolution of the stressedthermal capacities continues to be slow,with actual resolution of around 2GW onlyso far. Clearly, buyers remain focused onassets that have significant tie-ups on fuelsupply and long-term power purchaseagreements. The resolution also remainsslow due to significant hair-cuts beingsuggested, presence of multiple lendersand issues related to the settlement of pastcapex dues for the under-constructioncapacity.

However, the recent recommendationsof the high powered committee for the resolution of coastal ultra megapower projects, and the ultimate resolutionthereafter, if implemented successfully,may boost the PLFs for these plants,as they would see a sharp reduction inlosses. �

BY INVITATION

High conductivity copper (HCC) is the first choice for the manufacture of bulk

conductors such as cables, busbars, transformer windings and motor stators and rotors. However, for other electrical applications, such as connector parts, commutators and catenary wires, mechanical properties of HCC need to be enhanced by the addition of appropriate alloying elements. The ease with which copper can form alloys with other elements results in the availability of a very wide range of materials suitable for all electrical applications.

The tensile strength, proof stress and hardness of wrought HCC increase proportionately with the degree of cold working. If a stronger grade of HCC is required then it is alloyed with small amounts of silver. The addition of 0.03 per cent of silver makes it suitable for the production of transformer and other winding strips with controlled proof stress. For applications requiring good softening resistance during hard soldering, such as commutators, and where conductors are required to operate at higher than normal temperatures without loss of strength, such as large alternators and motors, 0.06-0.08 per cent silver is required. The softening temperature is raised by approximately 100K. Adding 0.08-0.12 per cent silver gives very good resistance to creep and is suitable for use in highly stressed rotor winding strips. Other applications are overhead collector wires for the catenary systems of railways and tramways. The conductivity of these alloys is 100 per cent International Annealed Copper Standard (IACS).

Tin, zinc, aluminium, manganese, nickel, and silicon can also be added to strengthen copper.

Alloying with beryllium creates the hardest and strongest copper alloy with mechanical properties

similar to high strength steels but non-magnetic and with better corrosion resistance and higher electrical conductivity (16-65 per cent IACS). It has excellent fatigue resistance. Copper beryllium is used for connectors, contacts and relays, all of which are subject to cyclical loading. It can be replaced by copper-nickel-tin in many applications.

Where a large amount of repetitive machining at high rates is required

such as for screws, fasteners, contacts, connectors, clamps and bolts, the addition of approximately 0.5 per cent tellurium or sulphur raises the machinability rating from 20 per cent to 90 per cent, based on a scale where free-machining brass is rated at 100 per cent. The electrical conductivity remains largely unaffected at 93 per cent IACS.

Copper-chromium alloys are commonly used as bars for high strength conductors. As castings (with up to 90 per cent IACS) they find application as electrode holders in resistance welding, and electrical termination equipment where the shape required is more complex than can be machined economically.

MICROGRIDS

The groundbreaking ceremony of ABB microgrid with battery energy storage at the campus of Indian Institute of

Technology, Roorkee (IITR) in Uttarakhand, was recently held. This is part of the larger R&D collaboration outlined in an MoU between ABB and IITR signed in July, 2018. The agreement for technology collaboration also includes the creation of a Smart Grid Resource Centre, joint R&D facilities and support for PhD students.

The smart campus development, in addition to the microgrid, would include technology solutions like smart metering, SCADA, ring main unit (RMUs) and a backbone of wireless broadband communication platform. It aims to create an operational smart grid network integrating all sources of energy including diesel generation and renewable energy. Another objective is to create a research platform to meet the requirements of the evolving grid like bi-directional flow of electricity with localized generation and enhance environmental awareness to influence consumer behavior to maximize usage of clean energy. This will serve as one of the pilot projects for Government of India’s Smart Cities Mission. The project cost is being partially funded by

ABB India under its CSR initiatives.IIT Roorkee currently has solar PV systems

installed at 27 locations across the campus amounting to 1.8 mw of solar generation. When the 11kV ABB AbilityTM PowerStore microgrid is commissioned in 2020, ABB’s advanced microgrid technology will enable the institute to increase the use of renewable energy, identify potential of demand side control, and integrate other power sources. The ABB AbilityTM Microgrid, SCADA, and smart metering will enable complete remote monitoring and maintenance, as well as visualization of overall energy requirements of the campus.

“This is yet another milestone and we are privileged to work with IIT Roorkee to set up a microgrid in the oldest engineering college campus in the country. With green energy becoming the preferred choice,

grid edge technologies such as microgrids are becoming a viable option to harness renewable power for smarter, inclusive and sustainable cities and also to provide access to reliable power in communities, campuses, or in remote or off grid areas,” said Pitamber Shivnani, President, Power Grids, ABB India. “This microgrid, along with the smart grid model, which will be set up on campus, will demonstrate the future of power.”

IIT Roorkee has done pioneering work in recent years to build an eco-friendly campus using renewable sources. The goal is to become a self-sustaining and zero emission green campus.

“Sustainability through adoption of new technologies has been at the core of all developmental activities at IIT Roorkee. We believe this collaboration with ABB using the IIT Roorkee campus as the hub for R&D on futuristic technologies for smarter, sustainable cities will create many milestones,” said Prof. Ajit Chaturvedi, Director of IIT Roorkee. “The microgrid is one such important element and the smart electricity distribution network and management system that we are undertaking will enable us to create a 100 per cent green campus and achieve zero carbon dioxide emissions in the long run.”

The advanced energy metering solutions will be used for energy accounting, billing and collection process. The metering solution will measure energy supplied by grid and diesel generators in separate registers to apply differential tariff, which will sensitize the campus residents/user community about the cost impact due to diesel consumption. ABB SCADA will offer the operator a centralized view of the grid condition and network snapshot. It will also enable power restoration swiftly from the central control, achieving minimum duration for power outage, thus improving availability. Retrofit of the ring main unit (RMU) will enable remote switching operation from the central command center and minimize people movement for manual switching. The wireless broadband communication backbone will pave the way to integrate other services on a common platform, which will be on the lines of an operating model of a smart city. �

TECHNOLOGY

To prevent the necessity of switching off electrical networks for maintenance services, it is obligatory to develop safe

and practical techniques that would allow the continuous flow of electrical supply to end consumers, by reducing the risks and minimizing the costs for the distribution utilities.

In the absence of such available live line technique for distribution lines in India, utilities generally follow a concept of breakdown maintenance rather than applying a smart preventive maintenance fundamentals widely adopted worldwide. With liberal open access policies established by the Central Government in recent years, individual consumer or consortium are free to swap their parent supply providers with a new distribution company which ensures uninterrupted quality supply particularly in a profit making industrial and commercial pockets. Therefore, there is a certain risk of losing major revenue making consumers in coming years particularly in industrial areas and cities.

Live-line maintenance plays a vital role in bringing down the outages substantially along with breakdowns through systematic implementation of condition monitoring and preventive maintenance schedules with an optimum use of human resources. Live-line working improves prestige of the company, providing top class services to precious customers by performing to their expectations. Live-line maintenance is a comprehensive solution for a distribution utility to work uninterruptedly on live lines, substations up to 33kV and DTCs using rubber gloves and hot stick techniques. It will definitely redefine the maintenance perception of Indian distribution companies from ‘breakdown maintenance’ to the well planned and cost effective ‘preventive maintenance’.

Rubber glove or barrier method: Linemen are equipped with appropriate personal and collective protective equipment (PPE and CPE), to isolate themselves from the hot and cold parts of the system, thus preventing the circulation of electrical current through body. It is important to observe that such technique is limited to the capacity of PPEs and CPEs. It is used on the electrical system

from 110V through 45kV.Hot stick or distance method: Linemen

are positioned on the structure or on a non-insulated or insulated work platform. They perform all tasks using insulated hot sticks. This technique can be used on systems of all voltage classes, as long as the electrical and mechanical characteristics of the equipment related to the voltage class of the line to be repaired are accomplished. So, on systems of voltage classes of 230kV and higher, due to the insulating distances, the equipment to be used become bigger, longer and heavier, making their use even harder.

Rubber glove or hot Stick method can be used separately or in combination in performance of activities comprising maintenance procedure according to the principles of the method of work like barrier and distance. This combination method consists of application of components from two different methods in one work process. Use of insulation arm, aerial work platform and other equipment will be required as per the scope of work.
