Q3. What is BDV of Transformer oil?
Ans. 
BDV stands for Breakdown Voltage. It is a measure of the dielectric strength of transformer oil.
• BDV is the voltage at which the insulation between two conductors breaks down.

• It is an important parameter to determine the quality of transformer oil.

• BDV is usually measured in kilovolts (kV).

• Higher BDV indicates better quality and higher dielectric strength of the oil.
