What is the role of transformer oil in a power company’s transformer?

The role of transformer oil in a power company’s transformer is to provide electrical insulation and cooling. Transformer oil effectively dissipates heat generated during operation, maintaining optimal temperature levels. Additionally, it serves as a barrier against moisture and contaminants, which can compromise the transformer’s performance and longevity. The chemical properties of transformer oil also prevent oxidation and enhance the overall reliability of the power company’s transformer.
