What are the technical aspects of transformer oil type?

The technical aspects of transformer oil type include its dielectric strength, thermal conductivity, viscosity, and chemical stability. Mineral oil is commonly used due to its excellent insulating properties and cost-effectiveness, while synthetic oils offer superior thermal performance and lower flammability. Additionally, the oil’s oxidation stability and moisture content are critical for maintaining transformer efficiency and longevity. Regular testing of these properties ensures optimal performance and safety in power transformers.
