Dual-channel DC Resistance Tester 10A
The transformer DC resistance tester is a necessary test item for semi-finished product, finished product factory test, installation, overhaul, change of tap changer, handover test and preventive test of power department in transformer manufacturing. The Dual-channel DC Resistance Tester can check the welding quality of the winding joint and whether there is inter turn short circuit in the winding, whether the contact of each position of the voltage tap changer is good, whether the actual position of the tap changer is consistent with the indicated position, whether the outgoing line is broken, and whether there is broken strand in the parallel winding of multiple wires. In order to meet the needs of fast measurement of transformer DC resistance, our company developed RDZR-10A DC resistance tester. The Transformer DC Resistance Tester adopts new power supply technology, which has the characteristics of small volume, light weight, large output current, good repeatability, strong anti-interference ability, perfect protection function and so on. The whole dc resistance meter is controlled by high-speed single-chip microcomputer, with high degree of automation, automatic discharge and discharge alarm function. The DC Resistance Analyzer has the advantages of high precision and easy operation, and can realize the fast measurement of transformer direct resistance

Measurement Method of Transformer DC Resistance
The DC resistance of a transformer refers to the DC resistance value of each phase winding. The purpose of measuring the DC resistance of a transformer is to check the welding quality of the winding joints and whether there is a short circuit between the winding turns; to check whether the contact of the tap changer is good and whether the actual position of the tap is correct.
