What is the function of transformer oil?

The function of transformer oil is to provide electrical insulation and cooling for power transformers. It prevents arcing and dielectric breakdown by insulating the internal components. Additionally, transformer oil dissipates heat generated during operation, maintaining optimal temperature levels. It also serves as a medium for the removal of moisture and contaminants, ensuring the longevity and reliability of the transformer. Proper maintenance of transformer oil is crucial for efficient transformer performance.
