ABSTRACT:
The present invention relates to a control system for automatically reconnecting power to customers in a distribution automation multi-feed power network on a fault disconnecting customers in the network. This invention provides the simple switching architecture with local control means that are implemented in the event of a fault. Each switch in the system has an intelligent switch controller which results in a faster restoration time which reduces customer down time in the event of a fault in the network. The system operates without the need for complex communication systems or central controllers. Each intelligent switch controller has the ability to cause its respective switch to open or close in the event of a fault. The network may be restored in a sequential manner subsequent to the detection of a fault in the network thereby allowing for the simple detection of the location of a fault.
