BDV (Breakdown Voltage) testing of transformer oil is conducted to assess the dielectric strength of the insulating oil used in transformers. The test involves applying a steadily increasing voltage across a sample of the oil until it breaks down electrically, indicating the maximum voltage it can withstand without failure. A high BDV value reflects clean, dry, and effective insulating oil, while a low BDV suggests contamination by moisture, dirt, or degradation products. Regular BDV testing is crucial for transformer health, as poor oil quality can lead to insulation failure, overheating, and reduced efficiency. It ensures safe and reliable transformer operation.
