Power Multi-Meter PQI120CP

UNDER DEVELOPMENT

The meter is geared to improvement of APCMS. PQI120CP 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.

PQI120CP is installed in the power quality monitoring and control systems for continuous monitoring of power quality indices of substations.
