What are the technical considerations for function of oil in transformer?

The technical considerations for the function of oil in a transformer include its role as an insulator and coolant. Transformer oil provides electrical insulation, preventing arcing between conductive components. Additionally, it dissipates heat generated during operation, maintaining optimal temperature levels. The oil’s chemical stability, dielectric strength, and moisture content are critical for performance and longevity. Regular monitoring of these properties ensures safe and efficient transformer operation.
