The DC resistance tester automatically performs discharge processing to eliminate inductive energy storage



The DC resistance tester, also commonly referred to as a transformer DC resistance tester or inductive load DC resistance tester, is a high-precision instrument specifically used for measuring the DC resistance of large inductive equipment such as transformer windings, generator stator windings, instrument transformers, and power cables.

It is the "stethoscope" for judging the quality of coil welding, the condition of inter-turn insulation, and the contact quality of tap changers in electrical equipment.
