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.

Please you select model T-213(single phase) or T-213S(three Phase).

T-203H THREE PHASE TRANSFORMER TURNS RATIO TESTER

GFUVE T-203H transformer turns ratio tester(TTR tester ) is a revolutionary instrument designed to perform three-phase turns ratio measurements using step-up excitation. A single three-phase lead-set connection is all that is required to complete three-phase tests in less than 1 minute! The T-203H is capable of three-phase excitation and can induce up to 160 V on the primary winding, overcoming the voltage dependence seen on larger transformers. The three-phase source also allows you to test phase shifting and zigzag transformers, and provides you with a guaranteed accuracy of ±0.1 % from -10 °C to +50 °C.
