What are the applications of transformer oil?

Transformer oil is primarily used as an insulating and cooling medium in power transformers. Its applications include reducing heat generated during operation, preventing electrical arcing, and providing insulation between live components and the transformer casing. Additionally, transformer oil helps to protect against moisture and contaminants, ensuring the longevity and reliability of the transformer. It also plays a role in dissipating heat, thereby enhancing the overall efficiency of the power transformer system.
