The breakdown voltage of mineral oil is a crucial parameter that indicates the oil’s insulating properties and its ability to withstand electrical stress without failing. Typically, the breakdown voltage for virgin mineral oil is around 30 kV per 2.5 cm, but this can vary based on factors such as the oil’s purity, contamination levels, and the presence of additives. Using testers like the Globecore Oil Breakdown Voltage Tester can help accurately measure this property, ensuring that the mineral oil remains effective for its intended industrial applications. Regular monitoring of the breakdown voltage is essential for maintaining the reliability and performance of electrical insulation systems.
