The dielectric breakdown voltage of transformer oil is a crucial parameter that indicates the oil’s ability to withstand electrical stress. Typically, transformer oils should have a dielectric breakdown voltage of at least 30 kV for a 2.5 mm gap, which signifies good insulating properties. However, this value can vary based on the oil’s purity, condition, and any contaminants present. It’s essential to regularly test transformer oil using a dielectric breakdown voltage tester to ensure that it is suitable for operation and to maintain effective insulation in transformers. Globecore offers reliable testing equipment designed to accurately measure the dielectric breakdown voltage of transformer oil, helping to assess its quality and performance in electrical applications. Regular monitoring of this parameter can prevent failures and enhance the longevity of transformer systems.
