What are the technical aspects of different types of transformer oil?

The technical aspects of different types of transformer oil include their chemical composition, dielectric strength, thermal conductivity, and viscosity. Mineral oils, commonly used, offer good insulation and cooling properties but may have lower fire resistance. Synthetic oils, such as ester-based fluids, provide higher fire safety and biodegradability. Additionally, natural esters have superior thermal properties and environmental benefits. Each type’s performance is influenced by these characteristics, impacting transformer efficiency and longevity.
