IVACE: A self-regulating variable Reactor

Inductance Variable Auto-Controle/spl acute/e a/spl grave/ Entrefers (IVACE) is a self-regulating variable reactor consisting essentially of passive components: magnetic cores with air gaps, four windings, and a diode bridge rectifier. Originally designed for use as a static var compensator, it is now used by Hydro-Que/spl acute/bec near its 735-kV transmission lines as a new voltage regulator for the overhead-ground-wire supply system for the utility's microwave stations in remote areas.
