What does dielectric strength of transformer oil mean?

Dielectric strength of transformer oil refers to the ability of the oil to withstand electric stress without breaking down or conducting electricity. It is a crucial parameter in ensuring the insulation properties of transformer oils, as high dielectric strength indicates the oil’s effectiveness in preventing electrical discharges that could lead to equipment failure or short circuits. Proper measurement and maintenance of dielectric strength are essential for the reliability and longevity of transformers and electrical systems.
