Abrégé

Various embodiments are described herein for methods and systems of regulating incoming voltage supplied from a utility power supply to a load. In one example embodiment, a voltage regulator adapted to be electrically interposed between the utility power supply and the load, each having at least one phase, is provided. The voltage regulator comprises an autotransformer having, for each phase, a series winding and a regulating winding, where the regulating winding has a plurality of taps and the series winding has a load side for connection to the load and a supply side for connection to the utility power supply. The voltage regulator comprises a controller coupled to the autotransformer, where the controller is configured to operate the voltage regulator in a zero voltage reduction mode and an autotransformer mode, and where the controller comprises a zero voltage reduction mode switch connected across a first subset of at least two taps of each regulating winding and a normally closed contactor connected across a second subset of at least two taps of each regulating winding.

Abrégé

A tap-switching autotransformer for regulating the voltage supplied to a facility includes an electronics sub-assembly for controlling switching of the taps. The electronics sub-assembly and the windings are contained in a housing from which the electronics sub-assembly may be removed for repair or replacement. The electronics sub-assembly is adapted to enable an electronically actuated switch to short-circuit two of the taps. A mechanical switch enables a separate short-circuit to be maintained between the taps to enable the electronics sub-assembly to be safely removed from the housing.
