Eleventh harmonic filter is he best way to eliminate eleventh harmonic distortion of the power system, at the same time to generate reactive power in the fundamental frequency.

Characteristics of eleventh harmonic filters and reactive power compensation

1. The eleventh harmonic filter circuit is made of reactors serial by capacitors. Capacitor of eleventh harmonic filter generated reactive power in the fundamental frequency. The circuit design for compensation according to the power factor; The inductance value choice of reactor is to series with the capacitor to form harmonic resonance, so that to establish a low impedance circuit to make most of the eleventh harmonics inflow the filters.

2. Each of eleventh harmonic filters includes a electromagnetism contactor, thermal relay, reactors and capacitors. Harmonic filters are usually connected to the main distribution cabinet by fuses feeder.

3. Control mothed of eleventh harmonic filters and the capacitor of automatic switching can be the same: The reactive power adjusted by the automatic power factor controller.

4. Eleventh harmonic filters is based on the customer's specific application requirements, using standard device to design, so that achieve the best power factor compensation and harmonic filtering characteristics through a reasonable investment.
