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

The technical considerations for the use of oil in transformers include its dielectric strength, thermal conductivity, and viscosity. The oil must have a high dielectric strength to prevent electrical breakdown and ensure safety. Adequate thermal conductivity is essential for efficient heat dissipation, while appropriate viscosity ensures proper circulation within the transformer. Additionally, the oil should have low moisture content and be resistant to oxidation to maintain performance and longevity. Regular monitoring of these properties is crucial for optimal transformer operation.
