BDV test means the Breakdown Voltage Test. It is done for checking the dielectric strength of the oil of the Transformer. Dielectric strength means the maximum capacity to withstand the voltage of insulating oil. ... For the purpose of BDV test, oil sample from the Transformer is taken in a Sample Bottle
