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.
The Power Quality Analyser and Fault Recorder PQI-DE for low, medium and high voltage networks is
the central component of a system with which all measurement tasks in electrical networks can be
The PQI-DE can be used as a Power Quality Interface according to power quality standards such as
IEC61000-2-2 / EN50160 or to check the technical connection guidelines such as DIN VDE AR 4110 and
DIN VDE 4120 and many more.
