Product description
Product parameters
Features:
● The instrument is a high-precision test instrument that integrates energy meter calibration, electrical parameter testing and power quality problems such as waveform distortion, voltage fluctuation and three-phase unbalance in the power grid.
● Accurately measure voltage, current, active power, reactive power, phase angle, power factor, frequency and other electrical parameters to calculate the measurement error of the test equipment loop;
● Display the vector of the measured voltage and current. The user can analyze the vector diagram to get the correctness of the wiring of the measuring device. At the same time, in the three-phase three-wire connection mode, 48 kinds of wiring modes can be automatically judged; the automatic calculation function of the charge-recovery power is convenient for the user to calculate the charge-recovery power for the user who has the problem of wiring;
● Measurement and analysis of the AC power quality supplied by the utility grid to the customer. Measurement and analysis: frequency deviation, voltage deviation, voltage fluctuation, three-phase voltage allowable imbalance and grid harmonics.
