Transformer Winding Resistance Meter-1

Transformer Winding Resistance Meter-1

Transformer Winding Resistance Meter-1 is an essential test project during transformer transfer, repair and changing tapping switch. Measuring DC resistance of transformer winding, you can check out weld or connection quality of down-lead, the winding inter-turn short circuit or open circuit, and whether tap-changer is well contacted. In the previous it is generally to use QJ44 double bridge to measure DC resistance, but the measuring current for this type of bridge is mA level current. So measurement will take a long time, and accuracy is lower. In order to change the above situation, our company has developed HTZZ-1A DC Resistance Rapid Tester.
