Transformer oil purification is a process to remove sludge, dissolved moisture and dissolved gases from the oil.

Before we move to process details, Lets see why transformers need purified oil  ?

Need for transformer oil filtration

As discussed in details Advantages of transformer oil filtration  in post why transformer oil filtration is required? here we will see in brief advantages for transformer oil purification :

  • Improved insulation properties of the oil and hence the other media like paper/cellulose insulation
  • Better the insulation of transformer, longer the life of the transformer and lesser the breakdown of the transformer
  • Longer the life of the transformer asset, good returns on investment of the asset
  • Lesser breakdowns and failure of the transformer results in uninterrupted power supply

For good performance of transformers we require filtration machines designed and manufactured with standards. At NACH we manufacture Oil purification machines with Standard (BIS, NEMA, IEEE, IEE, ASTM, ASME, IEC) for good performance of transformer.

 

Now lets move to, Transformer Oil Purification Procedure

Transformer Oil Purification Procedure

Transformer is one of the main asset in the electrical power industry which needs to be maintained for guaranteed uninterrupted power transmission in order to get assured revenue benefits.

Transformer life mainly depends on the quality of oil volume it contains.

Regular transformer oil filtration assures long and consistent results from the transformer.

 

Transformer oil purification is a process to remove sludge, dissolved moisture and dissolved gases from the oil. Transformer oil conditioning may also include to some extent improving the acidity of the oil.

A good oil purification system is able to deliver filtered oil with parameters as per the standard specification.
