A series tuned harmonic filter is a combination of inductor and capacitor designed to trap a certain harmonic. These filters are applied in parallel with the power system and is often called shunt passive filters. For most harmonic filters in power systems, filters are tuned to 4.2 or 4.7 for trapping 5th order harmonics.
