What are the uses of transformer oil in power transformers?

Transformer oil in power transformers serves multiple critical functions. Primarily, it acts as an insulating medium, preventing electrical discharges between conductive parts. Additionally, transformer oil facilitates heat dissipation, absorbing and transferring heat generated during operation to maintain optimal temperature levels. It also plays a role in preventing oxidation and moisture ingress, thereby enhancing the longevity and reliability of the transformer. Overall, transformer oil is essential for the efficient and safe operation of power transformers.
