OEM Best Pure Wave Generator Manufacturer – GDZRC-100U Transformer DC Winding Resistance Tester – HV Hipot
OEM Best Pure Wave Generator Manufacturer – GDZRC-100U Transformer DC Winding Resistance Tester – HV Hipot Detail:
General Information
Transformer DC winding resistance is a required test item for the factory test, installation, overhaul, change of tap switch, handover test and preventive test of power department. It can check the welding quality of the winding joints and whether there is a short-circuit between the windings. It can detect whether the contact of each position of the voltage tap switch is good, and whether the actual position of the tap switch is consistent with the indicated position, whether there is a fracture of the lead wire, whether there is a broken strand of multi-strand wire and winding.
GDZRC-100U Transformer DC Winding Resistance Tester is designed in order to meet the needs of rapid measurement of transformer DC winding resistance. The instrument adopts a new power supply technology, featuring small size, light weight, large output current, good repeatability, strong anti-interference ability and perfect protection function. The whole machine is controlled by high speed single chip microcomputer, high automation, with automatic discharge and discharge alarm function. The instrument has high precision and easy operation, which can realize the rapid measurement of transformer DC winding resistance.
