Ultra high vacuum type oil purifying and filtration plant is ideal for determining oil leakage in power transformer and reconditioning of used oil in EHV class power transformer shunt Reactor and other oiled filled equipments. The process used by experts is simple to perform. They first heat the oil and then pass it through the well-designed filter and later, it is treated by vacuum, which further dehydrate and degasify the oil to meet certain specifications-

  Parameters   Before Conditioning   After Conditioning
  Removal of Moisture   100 PPM   3 PPM 
  Removal of dissolved Gases   10% by vol.   0.1% by vol.
  Break down voltage   20 KV   70 KV
  Vacuum level of degassing   -   0.1 mbar
  Chamber   -   -
  Filtering capacity   Many micron   1 Micron
We design transformer power plant to meet the IS-6034 1989 standards with the latest modification or revision. The design helps in achieving high vacuum and low temperature of transformer oil. We intend the plant to feature independent pumping system that is also used to degas chamber.

The plant is equipped with control and indication panel that comes with complete automation and is made with weatherproof to ensure safe transformer service. To ensure successful servicing of transformer, our experts have assured the customers that all the components used for constructing transformer have the desired strength and rigidity to withstand several conditions of handling transport. During repairing of transformer, we ensure that the parts don’t have any corners or edges to avoid any injury during usage.

The plant includes the following components –

Inlet pump

While starting repairing, electrically driven positive displacement gear pumps of 6500 LPH capacity will be offered. The pump we use in the device is tested and is ideal for continuous trouble free operation during the complete overhauling process. It has automatic protection against over pressure.

The oil inlet pump has interlock arrangement and the heater to minimize energy loss and oil leakage. Unless the inlet pump is on, heaters cannot be energized. Interlocking arrangement will be offered in the Filter Plant between the Inlet pump and High level float switch, to avoid excessive rise of oil in the degassing chamber.

Magnetic Strainer preliminary filter

The transformer servicing also includes the procedure of magnetic strainer that is offered to prevent any type of damage to the inlet pump. It has the capacity of retaining all particles with more than 0.5 mm size and all magnetic particles. So, the incoming oil will pass through this filter and avoid oil leakage. The strainer used can be cleaned without taking the filter out from the pipeline.


Heaters are used during the servicing period to protect tubes from overheating, hot spot, and breaking of oil. Heaters are able to heat oil from ambient temperature to 800 C. Temperature during degassing and dehydration process is maintained by experts within 60 degrees C for deriving good results.

Pre filters

There is a filter cartridge used for eliminating the contaminants above 10-micron size. The unit is installed with vent and drain valves, pressure gauge at inlet and outlet and other necessary accessories. Necessary bypass system will be offered with valve.

Degassing chamber – two stages

The degassing chamber is a welded M.S. construction offered with the twin objective of expelling dissolved gases and humidity from the transformer oil. The chamber has ability to withstand the vacuum. The air valve installed in the degassing chamber lowers the vacuum when excessive foaming in the oil occurs.

Other parts are Ionic Reaction Column, vacuum pumping system, mechanical booster pump, micro filter and air compressor, oil extraction pump, control panel, and electrical system.
