Description

A line reactor is a 3 phase series inductance on the line side of a variable speed drives. Line reactor are available in various values of percent impedance, most typically 3% to 5%. Line reactor offer an economical solution to variety of problems especially in variable speed drive installations. It is applicable to either the input or the output of the drives.

Filtering with Holly line reactor provides the following advantages :

To add line impedence
To provide some light buffering against low magnitude line spikes
To reducing harmonics
To compensating for a low inductance motor
To increase the life span of semiconductor
