Double Clamp Digital Phase Voltmeter

/ETCR4020 Large Caliber Double Clamp Digital Phase Voltammeter

ETCR4020 Large Caliber Double Clamp Digital Phase Voltammeter

In the case of the tested circuit is not open-loop, measure two AC voltages, current, phase between voltages, phase between currents, phase, frequency, phase sequence, active power, reactive power, apparent power, and power factor between voltage and current. Discriminate the transformer wiring group, inductive and capacitive circuits, test the secondary circuit and the busbar protection system, read the phase relationship between the CTs of the differential protection groups, check the wiring of the meter for correctness, and repair the line equipment, etc.
