WebMay 1, 2009 · One of the simplest methods of dealing with harmonics is to place a sine wave filter on either side of the VFD. On the line side, these are typically called line reactors and have reactance values anywhere between 1.5% and 5.0% impedance. Higher impedance not only stops more harmonics, but it also limits the power going to the VFD. WebDec 18, 2024 · A line reactor (also referred to as a “choke”) is a variable frequency drive (VFD) accessory that consists of a coil of wire that forms a magnetic field as current flows through it.
