What is the role of transformer oil in a 300 kVA oil-filled transformer?

The role of transformer oil in a 300 kVA oil-filled transformer is crucial for both insulation and cooling. Transformer oil provides electrical insulation between the live components and the tank, preventing electrical breakdown. Additionally, it absorbs and dissipates heat generated during operation, maintaining optimal temperature levels. This dual function enhances the efficiency and longevity of the transformer, ensuring reliable performance in power distribution applications.
