What is the BDV value of 11kV transformer oil?

The BDV value of 11kV transformer oil typically ranges from 30 kV to 50 kV, depending on the oil’s quality and condition. Breakdown Voltage (BDV) is a critical parameter for assessing the insulating properties of transformer oil. A higher BDV value indicates better insulation performance, which is essential for the reliable operation of power transformers, preventing electrical breakdown and ensuring safety in electrical systems. Regular testing is recommended to monitor BDV values.
