HZ-3150A Touch Screen Portable Transformer Winding Resistance Tester 50A
HZ-3150A Touch Screen Portable Transformer Winding Resistance Tester 50A
Transformer DC resistance is the required test item of semi-finished products, finished product factory test, installation, overhaul, change of tap switch, handover test and power department preventive test of the transformer in transformer manufacturing. HZ-3150A Transformer Winding Resistance Tester can check the welding quality of the winding joint and whether the winding is an inter-turn short circuit, detect whether each position of the voltage tap switch is good, whether the actual position of the tap switch is consistent with the indicated position, whether the lead line is broken, and whether multiple strands are broken.
