VTSYIQI 10A Transformer DC Resistance Tester Transformer DC Resistance Meter with Resolution 1μΩ Output Current Automatic, 10A, 5A, 1A, 300mA, 100mA,<5mA Accuracy 0.2% Automatic Data Refresh Introduction DC resistance is a mandatory test item for semi-finished products, finished products 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 joints and whether there is any turn-to-turn short-circuit in the winding, whether the contact of each position of the voltage tap-changer is good and whether the actual position of the tap-changer matches with the indicated position, whether there is any fracture of the lead wire, whether there is any breakage of multi-stranded conductors in parallel winding and whether there is any breakage of strands, etc. The instrument adopts the new power supply technology.
