Solving all measurement tasks in electrical grids can be
a daunting task. The new Power Quality Interface and
Disturbance Recorder PQI-DA smart, aimed at low,
medium and high 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 defined/measured values in typical threephase systems.
