What is the BDV value of transformer oil as detailed in the PDF?

The BDV value of transformer oil, as detailed in the PDF, typically ranges from 30 kV to 70 kV, depending on the oil’s quality and condition. Breakdown Voltage (BDV) is a critical parameter that indicates the oil’s insulating properties. A higher BDV value signifies better insulation performance, which is essential for the safe and efficient operation of power transformers, preventing electrical breakdown and ensuring reliability.
