A BDV tester for transformer oil operates by measuring the breakdown voltage of the insulating oil under specific conditions. Typically, it involves placing a sample of transformer oil between two electrodes immersed in the oil. When a voltage is applied, the tester gradually increases the voltage until the point of breakdown occurs, indicated by a spark or flashover between the electrodes. The machine records the voltage at which this breakdown happens, providing a measurement that reflects the oil’s insulating properties, which are critical for the safe operation of transformers. The results help determine the oil’s quality and its ability to perform its insulating function effectively. Regular testing with a BDV tester is essential for maintaining the reliability and safety of electrical equipment.
