Products and solutions at a glance

PQSys – Permanently installed power quality monitoring systems

The PQSys product family consists of fixed installed power quality analysers, fault recorders and transient recorders for continuous monitoring of low, medium and high-voltage grids. They are primarily used by network operators and industrial clients to ensure compliance with voltage quality standards (e.g. EN 50160) and to analyse network disturbances.

PQMobil – Mobile grid analysers

The portable devices of the PQMobil series (PQ-Box ONE, 50, 150, 200 & 300) enable temporary grid analyses in the field. They are ideal for fault finding, condition assessment, or commissioning – particularly in distribution grids or industrial plants.

REGSys® – Automatic voltage regulation (AVR)

With the globally popular REGSys® voltage regulation system, A. Eberle offers an intelligent solution for controlling and monitoring transformers with tap changers. The systems ensure stable voltage conditions in medium and high-voltage applications in conventional and renewable energy generation plants or substations, and adapt flexibly to changing grid conditions.

LVRSys® – Low-voltage regulation

LVRSys® is a system for voltage regulation in low-voltage grids – serving as an alternative to traditional grid expansion. It enables grid operators to ensure a stable supply in the low-voltage grid even with high PV feed-in or load peaks, for example from electric vehicle charging stations.

EORSys – Earth fault regulation/-indication & current injection

The EORSys products detect and regulate earth faults and short circuits in medium-voltage grids, and safely and efficiently inject current. They are an integral part of modern protection and control concepts in power supply grids.

Power quality services – consulting & measurement services

In addition to its own measurement and regulation devices, A. Eberle offers comprehensive power quality services: from measurement planning and on-site execution to evaluation and interpretation of results. These services are aimed at utilities, industry, and operators of critical infrastructures.

Globally active – locally rooted

A. Eberle operates worldwide – with partners in over 60 countries. The devices are internationally certified and used on all continents. Through trade fair appearances, (online) training sessions, and global support, the company maintains a global presence and stays close to its customers.
