Line Reactors: Why and When You Should Use One?

WebReactors often serve to protect both motors and variable frequency drives (VFDs) from harmful current and voltage spikes by slowing the rate of current changes in the line via … Webload conditions. However, shunt reactors can reduce line loadability if they are not removed under full-load conditions. There are two general types of shunt reactors. One is dry-type reactor of an air core or core-less design. These reactors are limited to voltages up to 34.5kV and are often installed on the tertiary of a transformer. V(x) Vs
