T-213 20A transformer winding dc resistance tester with printer & 12m test cable

An important test item for measuring the DC resistance of transformer windings is ranked second in the transformer test items in the regulations. The purpose of measuring the DC resistance of transformer windings:

(1) Check the welding quality of the winding (2) Check for good contact at all positions of the tap changer (3) Check for any breaks in the winding or outgoing line (4) Check for the correctness of the parallel branch circuit, whether there is one or several wire breaks in the winding composed of several parallel wires (5) Check for short circuits between layers and turns.
