Wall-mounted AHF Module-Elecnova

Wall-mounted AHF Module

Active harmonic filter is a new type of electronic device for dynamic filtering of harmonic and reactive power compensation. It can conduct real-time filtering and compensation for harmonic distortion and dynamic reactive power, and is used to overcome disadvantages of conventional harmonic suppression and reactive compensation methods of the last generation of harmonic filters, thus realizing systematic harmonic filtering function and reactive power compensation function. In addition, it is widely applied into power, metallurgy, petroleum, port, chemical and industrial and mining industries.
