Abstract

An induction controlled voltage regulator, primarily for high-voltage regulation, includes a magnetic circuit based upon a core (1) having one or more flux paths or legs (2) surrounded by high and low voltage windings (3, 15). The leg (2) is divided in at least two branches (2A, 2B), at least one (2B) of which includes a regulation arrangement with a zone (5) of amendable permeability. The amendment of the permeability may be made by a magnetic rod (4) being movable into and out from the zone (5) formed as an airgap. Another embodiment for such an amendment includes the use of a regulator winding acting on the magnetic flux passing through the leg branch (2B). A compensator winding can be arranged around the leg branch (2B) involving the zone (5) of amendable permeability. The compensator winding is electrically connected in series with capacitor means. At least one of the windings is wound by a high-voltage cable comprising a conductor surrounded by an inner semiconductor, an insulator layer and an outer semiconductor.
