PQ Measurements – A.Eberle

A. Eberle is a pioneer in power quality, with a particular focus on tackling the challenges posed by supraharmonics, frequencies in the range of 9 to 150 kHz. These disturbances are becoming increasingly critical with the rise of modern power electronics, such as electric vehicle chargers and other front-end rectifiers. A. Eberle’s active participation in key industry working groups allows them to shape standards and stay ahead of evolving regulatory demands. Proud to be a frontrunner in the identification and mitigation of supraharmonics, A. Eberle continues to advance solutions that ensure grid stability and reliability.

Power Quality Mobile

The Mobile and Universal Power Quality Analyzer

PQ-Box 50

The perfect tool for energy management audits to ISO 50001. Our universal class a analyzer PQ-Box 50, has been developed for wide-ranging use and comes with an integrated power unit and robust housing, all in a small space. This network analyzer is for universal deployment and is ideal for mobile measurements in harsh environments or where space is highly limited.

The mobile Power Quality Analyzer

PQ-Box 150

The PQ-Box 150 mobile power quality analyzer, power meter and transient recorder was designed to quickly locate the source of network disturbances. The class A device was developed for measurements in low, medium and high voltage networks and is ideally designed for mobile measurement operation in harsh environments and in very confined spaces. Thus, the device impresses as a mobile all-rounder of our product group and its wide field of application, which also provides standard reports according to the specifications of EN 50160, IEC 61000-2-2/-2-4 for public and industrial networks.

The Mobile Power Quality Meter for Experts

PQ-Box 200

The mobile power quality meter PQ-Box 200 has been fitted with a wide range of triggering capabilities in order to rapidly locate the causes of network faults. The Class A device has been developed for measurements on low, medium and high-voltage networks and is ideally designed for measurements in harsh environments or where space is very limited. In addition, the device allows the power quality of public and industrial networks to be assessed. This means the device offers everything power quality experts need.

The network analyzer for high frequency ranges

PQ-Box 300

This mobile power quality network analyzer, power meter and transient recorder allows permanent DC frequency analysis to 170 kHz. The Class A device has been developed for measurements on low, medium and high-voltage networks and is ideally designed for measurements in harsh environments or where space is very limited. In addition, the device allows the power quality of public and industrial networks to be assessed. The device is thus an essential aid for analysis in high-frequency ranges.

Power Quality Systems

The fix-installed Tool for Power-Quality-Experts

PQI-DE

The PQI-DE is a voltage and power quality measurement device, fault recorder and residual current measurement device all in one. The device combines numerous functions. It can be used as a power quality interface to fulfil network quality standards or to check the technical connection guideline. It also offers SCADA interfaces and is fitted with a fifth power input. This means the device offers everything power quality experts need.

The fix-installed Power Quality Allrounder

PQI-DA smart

The PQI-DA smart is a voltage and power quality measurement device and fault recorder all in one. It has been developed for measurements on public grids, smart grids and in industrial environments up to 690V (L-L) measured voltage. The device can be used both as a power quality device and a measurement system to detect all the physical qualities of alternating current networks. This makes the device an appealing power quality all-rounder.

Secure, easy & economical for up to 16 feeders

»I-Sense« Feeder current measurement technology

With the new »I-Sense« technology for our fixed installed power quality analysers PQI-DE & PQI-DA smart, it is now possible to measure feeder current in the secondary substation securely, easily and economically for up to 16 feeders. The installation is easy and quick using Rogowski coils and, in addition to current measurement in the feeders, the system also offers the option of highly sophisticated power quality monitoring at the secondary substation transformer.
