What are the technical aspects of transformer oil temperature?

The technical aspects of transformer oil temperature include its critical role in heat dissipation and insulation. Transformer oil serves as both a coolant and an electrical insulator. Optimal operating temperatures typically range from 60°C to 90°C, with a maximum allowable temperature of around 110°C. Elevated temperatures can degrade oil quality, reducing dielectric strength and increasing the risk of insulation failure. Regular monitoring of oil temperature is essential for maintaining transformer efficiency and longevity.
