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: The present disclosure relates to a system for using load tap changing (LTC) transformers and voltage regulators (VRs) to more accurately reduce the voltage in a power transmission system. It further relates to a system for determining the operating mode for LTC transformers and VRs during reverse power flow. Corresponding methods are also disclosed. The various components of the present system, and the manner in which they interrelate, are more fully described hereinafter.

Abstract: A system for using load tap changing (LTC) transformers and voltage regulators (VR) to reduce the voltage in a power transmission system by temporarily disabling the upper band voltage and temporarily designating the bandcenter as the upper band edge voltage whereby the tap selector switches operate in set increments to reduce applied voltage to a level that is between the redesigned bandcenter and the lower band edge.

Abstract: A method for detecting the operating condition of each phase of a three-phase capacitor bank in a power distribution system, including the steps of, if the RMS neutral current is above the bank status closed setting, comparing the phase angle of neutral current (IN) with respect to voltage on one of the phases (VA, VB or VC) and sending an alarm signal when the comparison of the phase angle of neutral current with respect to the phase voltage differs appreciably from the expected phase angles.
