FRx-GSM network-analyzer

The COMTECH FRx-GSM allows statistical analysis of the work of low-voltage and medium-voltage networks. The device (using a proper voltage transformer) can be connected to busbars of 120 kV substations or MV/MV transformers, and to MV respectively LV consumption points.

Thanks to the compact design containing measurement circuit, communication unit and power supply, the device is able to work mobile or at a fixed site as well, so both the long term registration of voltage quality and finding failures casually are possible. The type FR3-GSM is optimized for measuring voltages on 3 phases, while the FR6‑GSM and FR9-GSM complete this with current measuring on 3 respectively 6 phases.
