Application examples of our products

Mains feedback interferes with protective devices

In a photography and design studio, located in a large industrial park, a RCD tripped frequently. Due to the permanent power cuts, the employees of the studio could not work properly. This article shows how we found a solution for this problem using our Power Quality devices.

Creating Power Quality surveys with PQ-Box and WinPQ mobil software

The following report displays the PQ-Box and WinPQ mobil software interact to allow an evaluation of the disturbance levels at a measuring point according to approved grid norms.

Measurement of voltage distortions in industrial grids with the PQ-Box 50

It is important to find disturbances in the system in a fast and reliable way. This report shows an example for trouble shooting with the Power Quality analyzer PQ-Box 50.

Power Quality Measurements: The Third Harmonic

This special publication intends to illustrate a typical power quality measurement and the aspects, which should be taken into consideration conducting the measurements.
