What is a line reactor and why is it needed

[drodriquez]

Guys,
What is a line reactor? and why do you need to use them in unison to variable speed drives?

A line reactor is a three-phase inductor generally installed in the AC input circuit of a drive (inverter) to minimize harmonics and to limit short-circuit current.

They are sometimes sold as an accessory or reactor kit with the drive. As a matter of fact you'll find reactor kits available more often than not.

Thanks, I have had some ghost problems in the recent past and I attempted to install line reactor kits thinking I was onto something, I didn't see a definitive difference for my issue in this case
