On 31. May 2023

Abstract The increasing market penetration of renewable energies is generally directly related to an increasing number of power electronic systems in the grid. Accordingly, a continuous change of the harmonic situation is to be expected depending on the operating state of the plants. Simulations are often not sufficient to represent the real situation of current […]

Measurements in all voltage levels up to 150 kHz – is that possible?

Posted by Neo Messtechnik
On 7. February 2023

A reliable energy supply has now become an important location factor for many companies. While in the past power failures and voltage fluctuations were among the most important parameters of supply quality, votlage transients or votlage harmonics are becoming increasingly important. This is mainly due to the ever increasing number of non-linear consumers and many […]
