What is the role of insulation oil in transformer operation?

The role of insulation oil in transformer operation is crucial for both electrical insulation and thermal management. It provides a dielectric barrier that prevents electrical breakdown between conductive components, ensuring safe operation. Additionally, insulation oil dissipates heat generated during transformer operation, maintaining optimal temperature levels. This oil also serves as a medium for moisture absorption and helps in preventing oxidation, thereby enhancing the longevity and reliability of the transformer.
