PQI120C is designed for revenue metering, measurement of power quality index (PQI), parameters of current, voltage, power, active and reactive power in 3ph mains and AC systems, as well as in points of meters mounting while keeping measurement results and displaying parameters of accounted electric power, PQI parameters and subsequent data transmission via communication interfaces. PQI120C is installed in the power quality monitoring and control systems for continuous monitoring of power quality indices of substations. Power Quality Measurement and Monitoring (Class A): – rms voltage; – frequency; – duration and index of ACF and overvoltage; – temporary overvoltage duration; – long- and short-term flicker indicator; – temporary overvoltage factor; – voltage n-harmonic component factor; – voltage waveform distortion factor; – negative-sequence voltage factor; – zero-sequence voltage factor. Multifunctional power meter (Class 0.2S): – metering of consumed active power based on cumulative total and separately according to rates; – eight rates; – active and reactive power; – active and reactive power loss; – energy recording malfunction flags.
