How is the breakdown voltage of oil measured?

The breakdown voltage of oil is measured using a specific device, often referred to as a dielectric strength tester, which applies voltage to a sample of the oil until insulation failure occurs. The Globecore oil breakdown voltage tester is designed to accurately assess the dielectric properties of industrial oils. This tester employs electrodes placed in the oil sample, gradually increasing the voltage until the oil breaks down, providing a clear measurement of the breakdown voltage. The results are crucial for determining the oil’s insulation quality and overall effectiveness in electrical applications.
