1. Testing (CT) current transformer: Open the machine and select the CT testing interface, choose the type of transformer such as M metering level, P level, etc; Check the options that need to be tested, such as excitation, transformation ratio, error, resistance, load, etc., and set the test parameters according to the transformer nameplate;

CT test wiring: Connect P1 and P2 to the primary side P1 of the transformer P2， Short circuit the yellow green S1 and connect it to the secondary side S1 of the transformer. Short circuit the black S2 and connect it to the secondary side S2 of the transformer. Turn the knob to start the test.

2. Testing (PT) current transformer: Open the machine and select the PT testing interface, choose the type of transformer such as M metering level, P level, etc; Check the options that need to be tested, such as excitation, transformation ratio, resistance, load, etc., and set the test parameters according to the transformer nameplate;

PT ratio test wiring: Connect P1 and P2 to the secondary side S1 of the transformer S2， Short circuit the yellow green S1 and connect it to the primary side P1 of the transformer. Short circuit the black S2 and connect it to the primary side P2 of the transformer. Turn the knob to start the test.

PT excitation test wiring: Short circuit yellow green S1 to the secondary side S1 of the transformer, short circuit black S2 to the secondary side S2 of the transformer;
