ABSTRACT:
A capacitor bank status monitoring, control and reporting system for use with a capacitor bank with “wye”-connected capacitors having a common neutral confluence and that can be switched in and out of a multi-phase high-voltage power distribution system. There is a first sensing device that detects the current flowing between the common neutral confluence of the capacitors and a common neutral wire of the distribution system and a second sensing device that detects the voltage of at least one sensed phase of the distribution system. There is an electrical device that controls the switched state of at least one of the capacitors. There is a controller, responsive to the first and second sensing devices, for providing reporting information concerning the status of the capacitor bank and concerning the determined voltage. A wireless communications system transmits the reporting information to a remote location, and receives information from the remote location and provides it to the controller.
