RSZR-01 Transformer Testing Equipment 10A Transformer DC Winding Tester Three Phase Digital Resistance Meter
The Transformer DC resistance test 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 winding. Direct-Circuit Rapid Resistance Tester 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.In order to meet the needs of rapid measurement of transformer DC resistance, RSZR-01 DC Resistance Tester is developed by our company.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 degree of automation, with automatic discharge and discharge alarm function.The instrument has high precision and easy operation, which can realize the rapid measurement of transformer resistance.
