Three-phase energy meter field calibrator
TT
More complete wrong wiring recognition functions, and IB access and reverse connection
of TV, TA polarity can be recognized;
TT
The instrument power is supplied with battery and test circuit, and can be online charged.
2.2 Main features
TT
Check the error of active and rewatt-hour meter at the same time, and meanwhile check
the error of main and secondary meter in the same circuit.
TT
Check the voltage, current, power, power factor, phase and frequency and other electrical
instruments and transmitters by contrast method.
TT
Identify 48 common three-phase three-wire, and 96 three-phase four-wire connection
errors in four quadrants, and show the hexagon diagram of any connection.
TT
Clip-on ammeter self-calibration function can guarantee the long-term accuracy stability of
clamp transformers. The self-test between any two phases ensures the long-term accuracy
stability of the instrument.
TT
to 51 three-phase voltage and current harmonics can be measured, and all harmonic data
can be stored.
TT
Display three voltage and current waveforms at the same time.
TT
Measure TV, TA secondary load.
TT
Store all measurement data of 6,000 meters, including operating parameters, to facilitate
subsequent analysis.
