Abstract: Method and apparatus for analyzing waveform signals of a power system. A waveform signal obtained from the power system is digitalized and then filtered. One or more segments are identified on the filtered waveform signal and, based on the information content of the identified segments, each of the one or more identified segments are classified as corresponding to a normal or abnormal condition occurred in the power system.

Abstract: A method and a protective device operable to perform the method are provided, wherein the method is for detecting and analyzing faults in a first cable and one or more other cables, which convey power in a three phase feeder system. Current magnitude in the first cable is compared to a threshold level. If the current magnitude exceeds the threshold level, the duration of the condition is measured. If the duration falls within a predetermined duration range, a predetermined time interval is allowed to pass and then a determination is made whether a fault is detected in the one or more other cables. If a fault is not detected in the one or more other cables, then a determination is made that a single phase fault has occurred in the feeder system.

Abstract: Automatic reclosing of a fault interrupting device is overridden by establishing communication with a control system (104) for a fault interrupting device (106) 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 (104) and having higher performance than the fault interrupting device control system (104), to determine whether to block the automatic reclosing of the fault interrupting device (106) before the fault interrupting device (106) automatically recloses. An autoreclosing block command is generated by the apparatus if the apparatus determines the automatic reclosing of the fault interrupting device (106) should be blocked. The autoreclosing block command is sent from the apparatus to the fault interrupting device control system (104) to prevent the automatic reclosing of the fault interrupting device (106) after the predetermined time delay.
