An oil dielectric breakdown voltage tester works by applying a high-voltage electrical charge to a sample of industrial oil to determine its insulating properties and dielectric strength. The tester consists of two electrodes immersed in the oil sample. When voltage is gradually increased, the tester measures the voltage at which dielectric breakdown occurs, meaning the oil becomes conductive and allows current to flow. This breakdown voltage indicates the oil’s ability to resist electrical breakdown, which is crucial for its performance in electrical systems. By assessing dielectric strength, users can ensure the oil’s reliability and longevity in operational conditions, thus maintaining the efficiency of equipment and preventing failures.
