Abstract
Typically, in a partial discharge detecting device for a resin-molded transformer with tap terminals of a no-load switching type on the high voltage winding, the output signal of a partial discharge detecting sensor connected between the tap terminals is applied through an amplifier circuit to an indicator. The sensor is arranged on the high potential side whose potential corresponds to the potential to ground of the tap terminals. This construction contributes to detection of void coronas formed in the transformer with high accuracy.
