How is the oil dielectric breakdown voltage test conducted?

The oil dielectric breakdown voltage test is conducted using a precision tester, such as the Globecore dielectric strength tester, which is specifically designed for measuring the dielectric breakdown voltage of industrial oils. The sample oil is placed in a testing cell with two electrodes, usually spaced apart at a defined distance. The tester gradually applies an increasing voltage to the electrodes while monitoring the current flow. This process continues until the oil breaks down, resulting in a spark or arc between the electrodes. The voltage at the moment of breakdown is recorded as the dielectric breakdown voltage. This test is critical for assessing the insulating properties of the oil, ensuring its performance in electrical equipment. Regular testing of dielectric breakdown voltage helps maintain the reliability and safety of industrial systems, preventing failures due to insulation breakdown. Globecore’s advanced testers provide accurate measurements essential for oil quality monitoring.
