Evidence by measurement of grid conformity of renewable energy plants

When your renewable energy plant was certified as grid compliant, limit violations of harmonic or interharmonic currents were detected which necessitate a resurvey of the harmonic current emission?

We will conduct the necessary retesting of the harmonics at the network connection point for you. For this we have the capable and high-precision measurement instrumentation of the manufacturers Dr. Haag Messgeräte and Dewetron at our disposal.

In order to eliminate any misunderstandings from the outset, we initially discuss the measuring or assessment processes in detail with the responsible grid operator. The measuring and measurement evaluation are conducted exactly following these instructions.

Upon completion of the measuring you receive a technical report in which the measuring results are comprehensively documented and evaluated.

If the resurvey shows that additional filter measures are required to limit the harmonic current emission, we will also do the basic and detailed engineering of the appropriate line filter on request. Since the filter also has an influence on the impedance-frequency response, the dimensioning of the filter will be agreed with the responsible grid operator.
