Winding Resistance Tester HYZC-20A
HYZC-20 winding resistance tester applied for DC resistance measurement of inductive specimen such as power transformer, motor, CT&VT and so on. The tester could also be applied for low resistance measurement such as contact or cable resistance. The device has a constant current source output that would charge the inductive specimen during testing. The charge of inductive specimen would make it enter saturation. And then the voltage drop of inductive specimen would represent the DC resistance voltage drop only. The device can measure this voltage drop of inductive specimen to get the exact DC resistance of the specimen.
