HV HIPOT GDZRC-10U 10A Transformer DC Winding Resistance Tester
Product Description
Transformer DC resistance is a must-test item in transformer manufacturing for semi-finished products, finished products factory test, installation, overhaul, after changing the tap changer, handover test and preventive test of the power department. It can check the welding quality of the winding joints and whether the windings have short-circuited between turns, also whether the contact of each position of the voltage tap switch is good, whether the actual position of the tap changer matches the indicated position, and whether the lead wire is broken, whether there is stock breakage, etc.
GDZRC-10U DC Winding Resistance Measuring Device is designed to measure DC resistance of inductive devices, such as transformers and power inductors.
Features
- Adopts two power supply modes: internal lithium battery and AC220V.
