Answer Posted / nissan patel gujarat
Insulating oil in an electrical power transformer is commonly known as Transformer Oil. It is normally obtained by fractional distillation and subsequent treatment of crude petroleum. That is why this oil is also known as Mineral Insulating Oil. Transformer Oil serves mainly tow purposes one it is liquid insulation in electrical power transformer and two it dissipates heat of the transformer e.i. acts as coolant. In addition to these, this oil serves other two purposes, it helps to preserve the core and winding as these are fully immersed inside oil and another important purpose of this oil is, it prevents direct contact of atmospheric oxygen with cellulose made paper insulation of windings, which is susceptible to oxidation.
Generally there are two types of Transformer Oil used in transformer,
1. Paraffin based Transformer Oil
2. Naphtha based Transformer Oil
