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.

Detection of current and voltage harmonics up to 9kHz

The power quality analyzer PQ-Box 150 measures current and voltage harmonics up to 9 kHz according to IEC61000-4-7. The device is well prepared for future power quality standards.



WLAN interface for wireless communication with the software & App

In addition to a USB and ethernet interface, the data recorded by the PQ-Box 150 can be transferred to the evaluation PC via a fast WLAN interface. The comprehensive evaluation software WinPQ mobil is included in the scope of delivery and can be installed on any number of PCs. To round off the user experience, we have developed the PQ-Box app for Android and iOS. For example, via the app it is possible to display a variety of online measured values, change transformer configurations for current and voltage transformers, the measuring interval or the nominal voltage of the PQ-Box 150.

All standards and protocols fulfilled – so our products are ready for the future

The PQ-Box 150 creates an automatic norm evaluation and event recording according to:

  • EN 50160
  • IEC 61000-2-2
  • IEC 61000-2-12
  • IEC 61000-2-4
  • NRS 048

Analyse faults in the ripple control telegram with ripple control analysis

The power quality analyzer makes it possible to trigger a ripple control frequency in addition to the ripple control level measurement and to record voltages and currents for a set frequency. The complete telegram can be displayed up to a length of 210 seconds and a variety of parameters can be set in the meter (trigger threshold, recording threshold, ripple control frequency, bandwidth of the filter curve for ripple control frequency).
