Product Description
I. It includes electric energy meter calibration、electrical parameters testing and waveform abnormality detection and so on electrical energy quality problem all in one high accurate testing equipment.
II. No stop、No change on metering circuit、no opening metering equipment, can online detect comprehensive error of metering equipment.
III. Accurately measure voltage,current,active power,reactive power,phase angle,power factor,frequency and so on many kinds of electrical parameters,thus calculate measuring error of equipment circuit.
IV. Can display sector graph of being tested voltage and current,use can check the correctness of equipment wiring through sector graph analysis. At the same time, it auto judge 48 kinds of wiring method when three-phase and three-wire connection.
V. Use split core type transformer to measure current circuit,no need to cut off current circuit, just do convenient and safe measurement.
VI. Can calibrate volt meter、ampere meter、power meter、phase meter and so on indicating instruments, and also for three-phase three-wire、three-phase four-wire、active and reactive power of 1A and 5A single phase.
VII. Can use photoelectric、manual、pulse and so on method to do the calibration of electric energy meter.
VIII. Measure and analyze the AC electric energy quality from public grid to end-user for:frequency deviation、voltage deviation、voltage fluctuation、flickering、imbalance of three-phase voltage and grid harmonic wave.
