Abstract:
    This invention discloses a method and a device for treating power net harmonics characterizing in utilizing a harmonic signal transmitter to separate sum of harmonic three-phase voltage or current signals to set that a harmonic transmitter secondary circuit formed by the controllable impedance at the secondary side of the transmitter costs harmonic energy, or inverses harmonic signals at the secondary side of the transmitter then feeds back the inverse signal to the system via the harmonic transmitter first side to cancel the harmonic volume of the system.
