dc resistance tachometer

The RDZR-10A 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. RDZR-10A Dc resistance tachometer 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 DC resistance test instrument 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 machine is controlled by high-speed single-chip microcomputer, with high degree of automation, automatic discharge and discharge alarm function. The DC resistance tester of transformer has the advantages of high precision and easy operation, and can realize the fast measurement of transformer direct resistance.
