What is paraffinic transformer oil and how is it used in power transformers?

Paraffinic transformer oil is a type of insulating oil derived from paraffinic crude oil, characterized by its high dielectric strength and low viscosity. In power transformers, paraffinic transformer oil is used as an insulating medium to prevent electrical discharges and to dissipate heat generated during operation. Its chemical stability and resistance to oxidation enhance the longevity and reliability of power transformers, ensuring efficient performance in electrical systems.
