Solving all measurement tasks in electrical grids today can be a challenging task. The new Power Quality-Interface and Disturbance Recorder PQI-DA smart, aimed at low- and medium-voltage grids, represents the A. Eberle response to such needs. This central component can be used either as Power Quality-Interface in accordance with all Power Quality standards or as a device for all physically measured values in typical three-phase systems.
Beside the possibility of standard evaluations, the PQI-DA smart also has a high speed fault recorder capability with a 40.96kHz recording rate and a half cycle r.m.s. registration, which allows detailed analysis of grid disturbances.
In particular, PQI-DA smart is suitable for monitoring, registering, evaluating and recording special reference quantities or quality agreements between the supplier of energy and the endcustomer.
