• Intelligence double clamp digital phase voltmeter,direct measurement of AC voltage(range: 0.00V~600V) and AC current (range:0.0mA~20.0A) 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. 5.With USB interface, Data storage: 1200 groups. Through the system software to upload the storage data to computer, convenient to read, save, report, print historical data, etc.
  • In the case of the tested circuit is not open-loop, Measuring three-phase AC voltage(0.00V~600V), current(0.0mA~400A), 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 CT of the differential protection groups, check the wiring of the meter for correctness, and repair the line equipment, etc.
  • In the case of the tested circuit is not open-loop, Measuring three-phase AC voltage, current, phase between voltages, phase between currents, phase, frequency, phase sequence, active power, reactive power, apparent power, and power factor and current vector sum.
