Abstract
Automatic reclosing of a fault interrupting device is overridden by establishing communication with a control system for a fault interrupting device operable to open responsive to a fault on an electric distribution system and automatically reclose after a predetermined time delay, and analyzing data for the electric distribution system by an apparatus separate from the fault interrupting device control system and having higher performance than the fault interrupting device control system, to determine whether to block the automatic reclosing of the fault interrupting device before the fault interrupting device automatically recloses. An autoreclosing block command is generated by the apparatus if the apparatus determines the automatic reclosing of the fault interrupting device should be blocked. The autoreclosing block command is sent from the apparatus to the fault interrupting device control system to prevent the automatic reclosing of the fault interrupting device after the predetermined time delay.
