How harmonic filters prevent distortions in networks with high harmonic …
With passive filters, the tuning frequencies of the filter steps are not precisely tuned to the harmonic currents to be filtered so that extremely high filter currents are avoided. In addition, passive filtering is not only possible in the range from the 3rd to the 25th harmonic, but also possible even beyond this.
