What are the technical considerations for transformer power oil?

The technical considerations for transformer power oil include its dielectric strength, thermal conductivity, viscosity, and oxidation stability. Dielectric strength ensures insulation effectiveness, while thermal conductivity affects heat dissipation. Viscosity influences the oil’s flow and cooling efficiency, and oxidation stability is crucial for prolonging the oil’s lifespan and preventing sludge formation. Additionally, moisture content and the presence of dissolved gases must be monitored to maintain optimal performance and reliability of the transformer.
