What is the introduction of transformer oil in power transformers?

The introduction of transformer oil in power transformers serves multiple critical functions. Transformer oil acts as an insulating medium, preventing electrical discharges between conductive parts. Additionally, it facilitates heat dissipation, ensuring that the transformer operates within safe temperature limits. The oil also protects against moisture and contaminants, enhancing the longevity and reliability of the transformer. Overall, the introduction of transformer oil is essential for optimal performance and safety in power transformers.
