ETCR4000 Double Clamp Digital Phase Voltmeter
Product Main Function

1. Direct measurement of AC voltage and AC current in the measured circuit which not open-loop, measure the phase between two voltages, two current and voltage current, and indirectly measure the power factor and power of the circuit. Distinguish three-phase phase sequence, transformer wiring group, inductive and capacitive circuit, test secondary circuit and bus differential protection system, Read out the phase relationship between each group of CT in differential protection, check whether the wiring of the electricity meter is correct or not, overhaul the line equipment etc.

2. Voltage Range:0~500V;

3. Current Range :0~10A;

4. Phase Range :0~360°;

5. CT Size:F8mm
