A harmonic filter inductor is a specialized inductor that is used in conjunction with power factor correcting capacitors. The harmonic filter inductor, when connected in series with the power factor correcting capacitors, will make a tuned LC filter at a specified frequency. This LC filter network can then be used to either filter out unwanted damaging harmonic currents, or set up as a “de-tuned” system to prevent parallel resonance between the power factor correcting capacitors and the inductive impedances on the power system.
