Description
Voltage up to 690 V (L-L) is measured directly; HV and MV networks are connected through voltage transformers. Transients are recorded from 24 µs. PQI-DE has 5 current inputs, monitors differential current up to 40.96 kHz and supports SCADA interfaces. Time is synchronised by GPS or NTP. Measurements follow IEC 61000-4-30, EN 50160 and IEC 62586, so the devices are suitable for continuous monitoring of public networks and smart grids.
