Transformer Oil Manufacturer

Divyol Transformer Oils are manufactured from carefully selected New Generation Right Base Oil with emphasis in product purity at every stage of refining. They have excellent cooling efficiency, longer life, better insulating properties, withstand extreme climatic conditions and are tested at independent laboratories of CPRI/ERDA/DOBLE /LABORELEC (ISO/IEC 17025:2017 ACCREDITATED LABS)

Transformer is a static machine which transmits power from one circuit to another. While doing so, a transformer gets heated up and at times, arcing or corona discharge takes place. To stop this and to insulate and dissipate the heat of the transformer, transformer oil is used. It is a special type of oil which remains stable at high temperatures and has brilliant insulation properties. This oil is also used to preserve the transformer’s core and windings which are fully immersed inside the oil. It also has the ability to prevent oxidation of the cellulose-made insulation.

There are two types of transformer oil - Naptha based transformer oil and Paraffin based transformer oil.
The naptha based transformer oil has a higher rate of oxidization i.e. it gets oxidized more easily than paraffin based oil. However, the resultant sludge produced by oxidization of naptha based oil is very soluble and hence it does not precipitate to the bottom of the transformer and therefore it does not block the flow of oil and does not hamper the cooling process. On the other hand, the sludge produced by paraffin based oil is insoluble and precipitates to the bottom of the transformer, obstructing the flow of oil. However, this is not an issue in warmer climate conditions such as in India.

A transformer is a static machine whose function is to transmit power from one circuit to another. While doing so, it gets heated up and at times, arcing or corona discharge takes place. To stop this and to insulate and dissipate the heat of the transformer, transformer oil or power transformer oil is used. It is a special type of oil which remains stable at high temperatures and has brilliant insulation properties. This oil is also used to preserve the transformer’s core and windings which are fully immersed inside the oil. It also has the ability to prevent oxidation of the cellulose-made insulation.

The colour of the transformer oil tells a great deal about how well the transformer is operating and what is the condition of the oil. It basically indicates the quality and age of the oil. Generally, fresh oil is pale yellow, orange or even red in colour and is transparent. As the oil ages, it slowly changes from a pale yellow, transparent colour to a deep brown, nearly opaque shade. Testing the colour of the oil also indicates its efficacy and efficiency. A dark shade indicates the presence of contaminants. Transformer oil manufacturers suggest that transformer oil needs to be changed or filtered as soon as it becomes dark in colour.
