What are the technical aspects of transformer oil immersed type?

Transformer oil immersed type transformers utilize insulating oil to cool and insulate the windings and core. Key technical aspects include the oil’s dielectric strength, thermal conductivity, and viscosity, which are critical for efficient heat dissipation and electrical insulation. The oil also serves as a barrier against moisture and contaminants. Regular testing for parameters like acidity, moisture content, and furan analysis is essential to ensure the longevity and reliability of the transformer.
