Harmonic Filter Reactors

MSI Harmonic Filter Reactor
Harmonic filter reactors, also known as harmonic trap reactors, are inductors used in the filtering of harmonics in a power system.  These harmonics are typically caused by non-linear devices in the power system.  We can design the harmonic filter reactor to a variety of fundamental frequencies and the accompanying harmonic content of your power system.
