An automatic oil breakdown voltage tester is a specialized device that assesses the dielectric strength of insulating oils used in electrical equipment. It works by applying a controlled voltage to a sample of oil until the point of breakdown occurs, which is indicated by a sudden drop in resistance. The tester features electrodes submerged in the oil sample, allowing direct measurement. As the voltage increases, the device continuously monitors the response of the oil. Once the dielectric breakdown takes place, the tester records the maximum voltage reached just before the breakdown, providing an essential indicator of the oil’s insulating properties. This measurement helps in determining the quality and suitability of the oil for use in transformers and other electrical equipment, ensuring safe and reliable operation.
