What are the specifications for oil filled transformers?

The specifications for oil filled transformers typically include dielectric strength, viscosity, flash point, and pour point of the transformer oil. Dielectric strength should be above 30 kV for effective insulation, while viscosity must ensure proper circulation at operating temperatures. The flash point should be above 140�C to minimize fire risk, and the pour point should be low enough to maintain fluidity in cold conditions. These specifications ensure optimal performance and safety of oil filled transformers.
