Harmonic Filters

ENTES Harmonic Filter Reactors are used in serial connection with capacitor banks in power factor correction units. By using these types of detuned reactors it is possible to increase the capacitor impedance against harmonic currents and to keep the resonance frequency under the frequencies in which main harmonic currents occur by shifting the resonance frequency.
