What are the technical aspects of transformer oil composition?

The technical aspects of transformer oil composition primarily include its chemical structure, dielectric strength, viscosity, and thermal stability. Transformer oil is typically composed of highly refined mineral oils, which contain aliphatic and aromatic hydrocarbons. Additives are often included to enhance oxidation stability, inhibit corrosion, and improve low-temperature performance. The oil’s dielectric properties are crucial for insulation, while its thermal conductivity aids in heat dissipation, ensuring efficient transformer operation.
