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. It 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.
RDZR-10AH Transformer DC Resistance Tester
