Abstract: A control system for a multi-phase power system includes a first phase line, a second phase line, and a third phase line. The control system includes a plurality of regulator controls including a first regulator control configured to control a first tap changer associated with the first phase line, a second regulator control configured to control a second tap changer associated with the second phase line, a third regulator control configured to control a third tap changer associated with the third phase line, and an electronic processor coupled to the first regulator control, the second regulator control, and the third regulator control. The electronic processor is configured to regulate the voltage of the multi-phase system using the first, second, and third regulator controls.

Abstract: A method for voltage regulation, control, protection and monitoring of state of on-load tap changers of power transformers, voltage regulators, and capacitor banks comprising: uses a voltage regulation system that has sets of voltage regulation parameters available for programming by a user. Each of these sets is adjustable in an independent manner for a given prevailing load condition. The parameters include a desired rated voltage at a load: a voltage variance percentage allowed over and below rated voltage; time delay adjustments for CDC (15) actuation in order to correct voltage; choice of linear or reverse time delay type; and parameters referring to voltage drop in the line.

Abstract: Embodiments of the disclosure pertain to a voltage regulator system having a voltage regulation controller and a transformer assembly. The transformer assembly includes a coil winding, a multi-contact tap arrangement connected to the coil winding, and a multifurcated tap changer system that includes a first tap changer having a contactor element which makes contact with a first contact of the multi-contact tap arrangement when the controller provides a positioning stimulus based on sensing a voltage deviation from a nominal output voltage of the voltage regulator system. The multifurcated tap changer system further includes a second tap changer that is mechanically ganged to the first tap changer and includes another contactor element arranged to automatically make contact with a second contact of the multi-contact tap arrangement when the contactor element of the first tap changer makes contact with the first contact of the multi-contact tap arrangement.
