TRANSFORMER OILS

Transformer oil (also known as insulating oil) is a special type of oil which has excellent electrical insulating properties and is stable at high temperatures. Transformer oil is used in oil-filled electrical power transformers to insulate, stop arcing and corona discharge, and to dissipate the heat of the transformer (i.e. act as a coolant).

Transformer oil is used to insulate high-voltage electrical infrastructure such as transformers, capacitors, switches and circuit breakers. Transformer oils are designed to operate effectively at very high temperatures, cooling, insulating, and stopping corona discharges and arcing.

What Is Power Transformer Oil?

Generally, the oil we use for the electrical power transformer insulation and cooling purpose is called the transformer oil or insulating oil. This oil used to collect through the partial distillation of crude petroleum. Now there are two main reasons for using this insulation oil in power transformers.

Transformer Oil is responsible for protecting the transformer’s main core and the winding. Transformer Oil also acts as insulation so that it could protect winding from direct contact with the oxygen and stop any kind of oxidation reaction.

There is another key point to use transformer oil in a power transformer. It absorbs the excess amount of heat when the transformer is operational and keeps the transformer cool from inside.

Transformer Oil Types

There are two main types of transformer oil used in transformers:

• Paraffin based transformer oil

• Naphtha based transformer oil
