FAM05/07

The modular FAM05/07 passive filter is made up of several filter steps, each based on a series resonant circuit, on the 5th and 7th harmonic order, between a capacitor step and a three-phase reactance. In this way, the harmonic currents tuned to the resonance frequency find a very low impedance in the filters and penetrate in a circular manner into the network of the installation. These filters are equipped with microprocessor control to control the insertion of the filter steps.
