Line Reactor Applications and Wiring Connections
Input Side of AC Drive
When installed on the input side of the AC Drive, line reactors will reduce line
notching, limit current and voltage spikes and surges from the incoming line, and
reduce the available short circuit current. The line reactors will also reduce
harmonic distortion from the AC Drive onto the line. Units are installed in front
of the AC Drive as shown.
Output Side of AC Drive
When installed on the output side of the AC Drive, line (load) reactors protect the
AC Drive from short circuits at the load. Voltage and current waveforms from the
AC Drive are enhanced, reducing motor overheating and noise emissions.
Single phase line reactors should not be installed on the output side of an AC Drive.
Use only three-phase reactors on drive outputs, and only for three-phase motors.
