Abstract
A system for controlling voltage including a transformer having a terminal, a plurality of windings and a plurality of winding taps. A voltage monitor coupled to the terminal of the transformer and configured to generate voltage data representing a voltage appearing at the terminal of the transformer. A non-bridging tap changer controller coupled to the voltage monitor and configured to generate tap changer control data for changing a configuration of a tap changer in response to the voltage data. A tap changer motor coupled to the non-bridging tap changer controller and configured to move the tap changer in response to the tap changer control data.
