What is the dielectric strength of transformer mineral oil?

The dielectric breakdown strength of transformer oil is a critical parameter that indicates the oil’s ability to withstand electrical stress without failing. Generally, the dielectric breakdown strength of high-quality transformer mineral oil can range from 30 kV/cm to 50 kV/cm, depending on its purity and composition. It is essential to regularly measure this property using testers designed for dielectric strength assessments to ensure optimal performance and safety of transformers. Globecore offers reliable testers for accurately determining the dielectric breakdown strength of transformer oil, ensuring that your electrical equipment operates efficiently and safely.
