High Voltage Testing Lab

High voltage test facility is available in the department

with the generator set up of 200 kV AC, 280 kV DC and 280

kV impulse voltages. Transformer oil testing facility up to

80 kV is established.

Testing facility has following set of equipments:

Capacitor divider rated for 200kV, 100pF (KVTEK).

H.W.S. Test System Bangalore make High Voltage Test

Transformers 140KV along with control panel.

Sphere gaps, Resistors, capacitors, diodes.

Connecting rods, insulating rods, connecting cups.

As transformer oil deteriorates through aging and moisture

ingress, transformer oil should, depending on economics,

transformer duty and other factors, be tested periodically.

Electric utility companies have a vested interest in periodic oil

testing because transformers represent a large proportion of their

total assets.

Through such testing, transformers' life can be substantially

increased, thus delaying new investment of replacement

transformer assets.

Transformer Oil Testing Lab

Transformer oil, a type of insulating and cooling oil used

in transformers and other electrical equipment, needs to

be tested periodically to ensure that it is still fit for purpose. This is

because it tends to deteriorate over time. Testing sequences and

procedures are defined by various international standards, many of

them set by ASTM. Transformer oil testing consists of

measuring breakdown voltage and other physical and chemical

properties of samples of the oil, either in a laboratory or using

portable test equipment on-site.

Why testing:

The transformer oil (insulation oil) of voltage transformers and

current transformers fulfills the purpose of insulating as well as

cooling.

Thus, the dielectric quality of transformer oil is essential to

secure operation of a transformer.

Field Plotter Hive Volta

The use of electrolytic devices for this purpose is well known. These

devices employ a pair of electrodes which are immersed into

an electrolytic solution contained in a tank. Successive null point

readings, i.e. equipotential points, are taken at various points between

the electrodes.


DC Machines

A DC motor is an electric motor that runs on direct current power. In

an electric motor, the operation is dependent upon simple

electromagnetism. A current-carrying conductor generates a

magnetic field, when this is then placed in an external magnetic field,

it will encounter a force proportional to the current in the conductor

and to the strength of the external magnetic field. It is a device which

converts electrical energy to mechanical energy. It works on the fact

that a current-carrying conductor placed in a magnetic field

experiences a force which causes it to rotate with respect to its

original position.

Input AC Voltage - 200V AC voltage

Single Phase and Three Phase Transformer

A single-phase or three-phase transformer is an electrical

device that accepts single-phase AC power and outputs

single-phase AC. This is used in the distribution of power in

non-urban areas as the overall demand and costs involved are

lower than the 3-phase distribution transformer. They are

used as a step-down transformer to decrease the home

voltage to a suitable value without a change in frequency. For

this reason, it is commonly used electrical power appliance at

residences.

Motor Generator Set

A motor generator (M-G) set refers to a composite device consisting

of a motor and a generator mechanically coupled through the common

shaft. Practically a motor generator set is a system where a motor and

a generator are connected or rather placed in a single circuit. It is a

device used to convert electrical power from one form to another.

That is mainly it converts electrical power to any other type of power.

Three Phase Slip Ring Induction Motor

The slip ring induction motor could be used for industrial wires

where variable speed and high starting torque are prime

requirements. The stator of slip ring induction motor is very much

the same as that of the squirrel cage induction motor, but the

construction of its rotor is very much different. Stator winding can

be either star or delta connected depending upon the design.

Induction with this type of rotor is having three phase double layer

distributed windings. Insulated enameled copper wires are used for

coils.

Power System Protection Schemes

IDMT Relay (Inverse Definite Minimum Time Relay) is

protection relay. They are used on transmission lines to see to that the

line current doesn't exceed safe values and if it does, triggers the circuit

breaker. IDMT means inverse definite minimum time.

Use of IDMT relay:

The relay will not operate when the value of current is less than the

pick value. The relay is used for the protection of the distribution lines.

The inverse time relay is of three types. The relay whose operating

time is approximately proportional to the fault current is known as

the IDMT relay.


Rectifier unit

A rectifier is an electrical device that converts alternating current,

which periodically reverses direction, to direct current, which

flows in only one direction. The process is known as rectification.

processor is in the automotive industry. The Cortex-M3 processor

has very high-performance efficiency and low interrupt latency,

allowing it to be used in real-time systems. The Cortex-M3

processor supports up to 240 external vectored interrupts, with a

built-in interrupt controller with nested interrupt supports and an

optional MPU, making it ideal for highly integrated and cost

sensitive automotive applications.

Data communications: The processor’s low power and high

efficiency, coupled with instructions in Thumb-2 for bit-field

manipulation, make the Cortex-M3 ideal for many

communications applications, such as Bluetooth and ZigBee.

Industrial control: In industrial control applications, simplicity,

fast response, reliability are key factors. Again, the Cortex-M3

processors interrupt feature, low interrupt latency, and enhanced

fault-handling features make it a strong candidate in this area.

Consumer products: In many consumer products, a high-

ARM Cortex M3 Evaluation Board

The ARM Cortex-M3 is a general purpose 32-bit microprocessor,

which offers high performance and very low power consumption. The

Cortex-M3 offers many new features, including a Thumb-2 instruction

set, low interrupt latency, hardware divide, interruptible / continuable

multiple load and store instructions, automatic state save and restore

Applications of Cortex M3 processors (Industrial

Relevance)

Low-cost micro controllers: The Cortex-M3 processor is ideally

suited for low-cost micro controllers, which are commonly used

in consumer products, from toys to electrical appliances. It is a

highly competitive market due to the many well-known 8-bit and

16-bit micro controller products on the market. Its lower power,

high performance, and ease-of use advantages enable embedded

developers to migrate to 32-bit systems and develop products

with the ARM architecture.

also be used for analyzing digital circuits. Both Logic

circuits and digital circuits are made up of integrated

circuits (IC’s) of 74XX TTL family. It can be used for

rigging- up complex circuits using two or more numbers of

IC’s at a time. Trainer kits provide needful flexibility for

conducting experiments.

DC Power Supply (Regulated)

Electronic circuits needing stable DC power supply of

different levels, for example biasing requirements of

transistor amplifier or to study the device characteristics

one way require variable DC in such cases Knob can be

operated to assign different levels of the voltage. Either

due to source variation or load variation the voltage level

may get affected therefore there is need of regulated DC

power supply.

Function Generator

Function Generator also identified as signal generators are

used for various experimentations where indentified

signal/signals are to be processed. Signal generator can be

used to set desired signal of sine/triangular/square etc

cosine shape of different magnitudes and frequencies.
