Abstract
Transformer oil acts as a cooling and insulating medium in transformers. This insulating oil not only fills up the pores in the fibrous insulation such as paper, but also the gaps between the turns of the winding and the spacing between the winding and the tank. The oil, in addition to functioning as a dielectric also serves as a cooling medium and also preserves the metal parts internally by submerging them. There are so many oils used in the transformers right from Mineral oil to vegetable oils. This paper highlights the latest trends in oil market by discussing advantages and disadvantages of each oil.
