Abstract: A system for load balancing on a multi-phase power line connected to a single phase lateral power line, includes a contactor configured to selectively connect each phase of the multi-phase power line to the single phase lateral power line. There is a phase change device connected in parallel with the contactor and a controller. During the phase change state, the controller connects the input of the phase change device to the multi-phase power line and connects the output of the phase change device the single phase lateral power line. The controller causes the phase change device to output a voltage to the single phase lateral line initially aligned with the first phase and then rotated to align with the second phase and causes the contactor changes connection to the second phase of the multi-phase power line and disconnect the phase change device from the power lines.

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 reactor pressure vessel supports the flanges of a core barrel assembly and an upper support plate. These flanges have aligned holes for diverting inlet coolant water to the vessel head for cooling the head. The aligned holes have different cross-sectional areas for controlling unexpected backflow of coolant water from the vessel head around the periphery of the upper support plate.
