Oil Breakdown Voltage: The BDV Test Explained (IEC 60156)
Of all the tests you can run on transformer oil, this is the one that gets run first. It’s fast, it’s cheap, and a single number in kilovolts tells you whether the oil is doing its main job: holding off voltage without arcing. The breakdown voltage test — BDV — measures the highest voltage the oil can take… Read More: Oil Breakdown Voltage: The BDV Test Explained (IEC 60156) »
