Transformer DC Resistance Tester

Type: ZC-205A
    DC resistance measurement of transformer winding is an essential test during transformer delivery, repair and changing tapping switch. Usually, it is a time consuming task to use traditional methods (bridge method and voltage step down method) to measure transformer winding and DC resistance of high-power inductive device. In order to change this situation: shorten measurement time and reduce the staff’s workflow, our company has developed ZC-205A Transformer DC Resistance Tester.
