What is the significance of transformer oil in the name of power transformers?

The significance of transformer oil in the name of power transformers lies in its crucial role as an insulating and cooling medium. Transformer oil prevents electrical arcing and breakdown by providing electrical insulation between live components. Additionally, it dissipates heat generated during operation, ensuring optimal performance and longevity of the power transformer. Thus, transformer oil is integral to the safe and efficient functioning of power transformers.
