Abstract
Automatically de-energizing and re-energizing a section of a distribution feeder circuit includes detecting, using a module of a protective device, whether a section of a distribution feeder circuit upstream of the protective device has been de-energized and whether the protective device may be opened automatically. The module signals for the protective device to be opened when the section has been de-energized and when the protective device may be opened automatically. The module also is used to detect whether the protective device has been opened and may be closed automatically, and whether the section of the distribution feeder circuit upstream of the protective device has stabilized. The module is used to signal for the protective device to be closed automatically when the protective device has been opened automatically and may be closed automatically, and when the section of the distribution feeder circuit upstream of the protective device has stabilized.
