How is dielectric strength of transformer oil defined?

Dielectric strength of transformer oil is defined as the maximum electrical field that the oil can withstand without breaking down, measured in kilovolts per millimeter (kV/mm). It is a critical property as it indicates the oil’s ability to insulate and prevent electrical discharges within transformers. Globecore offers various testers that can accurately measure the dielectric strength of transformer oil, ensuring that the oil maintains its insulating properties and operates safely under high-voltage conditions. Regular testing is essential for the maintenance of transformers and the protection of electrical systems, so utilizing quality testers like those from Globecore is highly recommended.
