The BDV oil test transformer is performed by taking a sample of the insulating oil from the transformer and placing it in a test cell specifically designed for this purpose. The test cell is then subjected to an increasing voltage until the breakdown occurs, which indicates the dielectric strength of the oil. During the process, electrodes are submerged in the oil sample, and the voltage is applied slowly while monitoring for discharge. The voltage at which the breakdown occurs is recorded, providing an essential measurement of the oil’s insulating properties. This test is crucial as it helps in predicting the reliability and safety of the transformer. Proper execution of the BDV oil test transformer ensures effective maintenance and minimizes the risk of transformer failure.
