What is the standard BDV test value for a transformer?

The standard BDV (Breakdown Voltage) test value for a transformer generally falls within the range of 30 kV to 60 kV for new transformer oils, depending on the specific application and manufacturer specifications. However, it’s crucial to ensure that the BDV value is consistently monitored over time, as values below 30 kV may indicate contamination or degradation of the insulating oil, necessitating further testing and potential maintenance. Utilizing a motwane bdv tester can provide accurate measurements and help ensure the reliability and efficiency of transformer operations, thereby aiding in preventive maintenance strategies.
