This device measures, checks and visualizes all the main electric parameters of an AC threephase electric line (A440 Series).

They store the data, with a programmable sampling time, and create an archive of measured and calculated electric parameters.

Every parameter (phase voltage, concatenate voltage, currents, active power, reactive power, apparent power, frequency, power factor, active energy, reactive energy, harmonic frequency) can be configured to activate an alarm/prealarm; for example, to establish beforehand the border line of electric power, to plan and manage efficiently the time slot profile of the energy contract.

The same device, can be also used to perform instead of 1 three-phase measure, 3 mono-phase measures.

This device can be potentially managed by supervision soft ware, with direct connection (stand-alone modality) or by inclusion in the Unicontrol peripheral monitoring system.
