Claim:
1. An apparatus, comprising: a communication interface operable to enable 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 a processing circuit having higher performance than the fault interrupting device control system and operable to: analyze data for the electric distribution system to determine whether to block the automatic reclosing of the fault interrupting device before the fault interrupting device automatically recloses; and generate an autoreclosing block command if the processing circuit determines the automatic reclosing of the fault interrupting device should be blocked, wherein the communication interface is further operable to communicate the autoreclosing block command to the fault interrupting device control system to prevent the automatic reclosing of the fault interrupting device after the predetermined time delay, wherein the data analyzed by the processing circuit includes a digital fault record received from the fault interrupting device control system via the communication interface, the digital fault record representing a time-domain snapshot of voltage and current waveforms observed at the fault interrupting device before and after the fault, and further wherein the communication interface is operable to:
