AC line reactors are added to the input of the drive and placed in series with the incoming line. They help to mitigate harmonics and because they are between the line and the drive, they are able to act as a buffer for surges and other transients. The intended purpose of a line reactor is not to offer high levels of surge protection and, if greater protection is desired, a dedicated protective device is a much better solution.
The disadvantage of an AC line reactor is that there is a voltage drop across them. This can cause under-voltage trips in systems where the input voltage is not as stable.
The benefits of ac line reactor usage are (Model: RWK 212):
-4% impedance reactors provide an excellent cost/benefit ratio and are particularly beneficiary in the most diverse motor drive applications.
-Reduction of mains harmonics
-Limitation of inrush currents
-Improvement of true power factor
