Power Quality-Interface and Disturbance Recorder PQI-DA smart



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.
The PQI-DA smart has been developed for measurements performed within public grids, for Smart Grid applications, as well as for recording PQ-data within an industrial environment up to 690V (L-L) measurement voltage. It also allows frequency measurement of voltage and current harmonics  according to IEC 61000-4-7 from 2 kHz to 9 kHz.
