Abstract
In a multiphase alternating current electric power system subject to erratic and unbalanced reactive load current demand, reactive load current compensation is provided by a balanced multiphase reactive compensating impedance having equal but limited reactive current capability in all phases. To increase reactive current capability of any one selected phase of the reactive compensator in response to severe load unbalance a supplementary single phase compensating impedance is connected through a load current controlled switching bridge in parallel circuit relation with any one phase arm of the multiphase compensator. When any one such parallel connection is operative the switching bridge is prevented from connecting the supplementary impedance in any other phase arm of the multiphase compensator.
