What are the technical considerations for oil used in transformer?

The technical considerations for oil used in transformers include its dielectric strength, thermal conductivity, viscosity, and chemical stability. The oil must have high dielectric strength to prevent electrical breakdown, efficient thermal conductivity for heat dissipation, and appropriate viscosity for optimal circulation. Additionally, it should resist oxidation and degradation over time to maintain performance and safety. Regular testing for moisture content and contaminants is also crucial to ensure the oil’s integrity and transformer reliability.
