Abstract:
1. A multi-phase operation voltage regulator controller, comprising: a main control module comprising a processor, electronically-controlled switches, and a user interface, the main control module being configured to automatically control a tap changer of a lead phase of a multi-phase power system using the electronically-controlled switches in response to a first control signal of the processor; a lineman module coupled to the main control module comprising a mode switch and a tap change switch, the lineman module being configured to manually control the tap changer of the lead phase using the mode switch and tap change switch; and an add-on lineman module comprising second electronically-controlled switches, a second mode switch, and a second tap change switch, the add-on lineman module being configured to automatically control a tap changer of a second phase using the second electronically-controlled switches in response to a second control signal of the processor, wherein the main control module is configured to automatically control the tap changer of the second phase using the electronically-controlled switches in response to the second control signal from the processor.
