Abstract: A low fault current isolation arrangement senses a loss of voltage and automatically isolates and de-energizes a down live primary wire if overcurrent protection devices have not cleared the high impedance fault in an electric power distribution network. Incorporating an operator selectable time delay response, the low fault current isolation arrangement permits overcurrent protection devices to attempt to detect and shut down the affected conductor, and then isolates and shuts down the low current fault if the overcurrent devices are not successful. The isolation arrangement continuously monitors AC voltage as remotely provided by smart meters even after a fault location is de-energized, and serves as a back up, and not as a replacement, for existing overcurrent protection schemes. A host computer operates in conjunction with plural smart meters each coupled to an associated customer distribution transformer in conjunction with the fault isolator to detect and shut down high impedance faults.

Abstract: Shipment and storage of systems poses integrity and economical issues. Such systems may require substantial packaging to protect components of the system during shipment and storage. Some components, such as a battery, may need to be separated from the system during shipment to prevent either actual or perceived damage by the user of the system. A battery directly connected to a system may discharge so as to be incapable of providing sufficient power to the system. Users may erroneously believe that the system is defective and place unnecessary service calls. Such service calls increase costs and affect future business activity. Configuring the terminals of high current connectors coupled to the battery and the system allow for an isolator to be inserted between the high current connectors to prevent conduction while allowing the connectors to mate which results in feasibly shipping the battery in tact within the system.
