Technical data

A perfect solution

The winding hot spot is one of the most critical parameters to monitor within a transformer. This temperature influences the life of the insulating material and thus the life-time of your transformer. Direct temperature reading with photo luminescent thermal sensors gives you the accuracy you need to better manage your assets.

Fiber Optic temperature measurement

Some applications:– Inside power transformers, measuring directly winding,

core or oil temperature – At the hottest part of the magnetic circuit in shunt reactors– Temperature testing of capacitors and resistors in high power applications– Monitoring of “live” electrical circuits during lifetime testing– Process monitoring in the chemical or semiconductor industry

What do you need?

"I need (up to) 4 inputs for winding or core temperatures and 1 Pt100 input for oil or ambient temperature. I need 2 free programmable analogue outputs and up to 6 contacts for alarm, trip and cooling control functions"

“I need in addition the CT nominal current to calculate the winding temperature, as I want to compare the values according to IEC and ANSI standards. I also like the oil level via 4-20mA signal”

“I need communication, might it be via Ethernet, RS485 or others. I like to implement protocols as DNP3.0 or others. Maybe in the future I like to connect other sensors”

“I need everything, say direct temperature measurement, calculation, intelligent cooling control and communi-cation with substation control room”

“I need a housing”

How does the direct measurement work?

The EPT202FO has 4 integrated high intensity long-life laser diodes which pulse into the optical fiber cable. These pulses are transmitted via the fiber optic extension cable and the transformer tank wall plate inside the transformer. The light from the laser diode excite the sensor at the end of the fiber optic cable. The sensor emits a light that returns back to the EPT202FO. The EPT202FO-Module determines the decay time in micro seconds. The decay time is directly related to the sensor temperature. As the decay time is an inherent material property this will never change. The system never requires a calibration. The used components are designed to match the transformer life time. It is also possible to change the sensors or the electronics without calibration.

Benefits:

• We measure the time decay, not the intensity of the returning light, because the decaying time is directly related to the sensor temperature• No calibration required (even if changing sensors or electronic devices)• High EMI compatibility due to non-galvanic sensors• High reliability• 25 years of experience

– Up to 4 probes to read directly each transformer winding or core temperature;typically the hottest winding temperature value will activate the fans or pumps

– Pt100 signal for top oil or ambient temperature– Freely scalable measuring range between -30 to +200°C– User-friendly PC software– Data logging– Lifetime consumption calculation as per IEC and ANSI standards– Intelligent cooling control;

fan running alternation to equalize operation time of the fans– Information visible on status, alarm, trip and state of fans via device LEDs– Extensive possibilities in combination with EPT202 OL/CT (calculated temperature

model) and/or IM modul (communication)– Measurement of signal intensity losses

Benefits– Accurate, direct temperature reading in the winding’s hot spot– Improves real time transformer loading capability– Allows verification of the transformer design characteristics (heat run test)

Fiber Optic experience

For more than 25 years, our partner LumaSense has been measuring winding hot spot temperatures. The ruggedized probes have been successfully used for years world-wide. Their solid state long life Fluoroptic® technology is recognized to be at the forefront. The cooperation with Messko gives you a proven solution from the leading companies in the market: direct winding temperature measurement with intelligent cooling control and all the different ways of communication.

The major advantages of the LumaSense Fluoroptic® technology are reliability and stability. Reliability comes from using only components that do not deteriorate with time (LED light source). Measurement stability comes from the physical fact that the decay time of the phosphor is an inherent material property and never changes.

In combination with the EPT202FO, this technology offers a proven solution to optimize power transformer operation. Since the Fluoroptic® fiber optic probes are EMI, RF and Microwave resistant and designed for high voltage applications, they can be placed practically everywhere in the transformer. They are typically completely immersed in hot transformer oil and withstand exposure to Kerosene vapor during the drying process. With over 25 years of experience, the LumaSense probes are worth of long term operations in transformers for decades. In addition LumaSense is ISO-certified.

Fluoroptic® fiber optic probes are installed in more than 3,000 power transformers world-wide. OEM's around the world have been trained by LumaSense experts on how to install the probes. Utilities like Salt River Project, Consolidated Edison or Southern California Edison use this technology in numerous transformers.

The EPT202 has been introduced into the market in 2003. Since then, customers around the world relies on this proven modular design concept. Different designs are available for customer-specific installation – at prices which are considerably less than having to buy expensive monitoring systems. Utilities like Provincial Electricity Authority in Thailand or Eskom in South Africa and major utilities in the US rely on the EPT202 as an important tool managing their costs.

If you buy a Messko device, you can be sure that it exceeds the demands of existing testing standards. Naturally, all devices of the EPT202 family have been tested for electrical safety, electro-magnetic compatibility and resistance to temperature and climatic conditions in accordance with the applicable standards.

Each device is delivered with a test certificate. This certificate lists all tests that the device has passed, together with important device data. Quality that you expect from Messko.

And not to forget: we proudly give a warranty of 5 years on this device, as for all the other products of the Messko range.

How to install

The thermal sensor (1) at the end of the fiber optic probe is placed in a spacer in the main, tapping or tertiary winding of the transformer. The exact place is determined by the transformer manufacturer who has calculated the hot spot area. On the other side the probe (2) is screwed onto the tank wall feedthrough plate (3). On the opposite side of the assembly, outside the transformer, an external fiber optic extension cable is connected (4) which then leads to the EPT202FO module (5).

This principle allows to install the probes independently. It is also possible to install more than 4 probes and cover the remaining at the tank wall penetrator. The type of the installed LumaSense probes has to be selected in the EPT202FO software.
