What is an oil breakdown voltage tester?

An oil breakdown voltage tester is a specialized device used to measure the dielectric strength of insulating oils. This tester determines the voltage at which an electrical breakdown occurs in the oil, which is crucial for assessing the oil’s quality and its ability to insulate electrical equipment. By applying a steadily increasing voltage to a sample of the oil, the tester identifies the breakdown point, providing valuable insights into the oil’s condition and suitability for use in transformers and other electrical devices. Proper maintenance and regular testing with an oil breakdown voltage tester help prevent equipment failures and ensure operational reliability.
