Line Reactors

MSI Line Reactor
Line reactors are AC inductors used to filter out current spikes, protect sensitive equipment such as variable frequency drives, and provide some short circuit protection in a power system.  They can also be used to filter out high frequency harmonic currents above the fundamental mains frequency of the power system.
