The pulse-recloser uses pulse testing technology to verify that the line isclear of faults before initiating a reclose operation, which significantlyreduces stress on the system components (e.g. substation transformers) andvoltage sags on adjacent feeders. Online event analysis of pulse-reclosers areessential to increases the overall utility of the devices, especially whenthere are numerous devices installed throughout the distribution system. Inthis paper, field data recorded from several devices were analyzed to identifyspecific activity and fault locations. An algorithm is developed to screen thedata to identify the status of each pole and to tag time windows with apossible pulse event. In the next step, selected time windows are furtheranalyzed and classified using a sparse representation technique by solving anl1-regularized least-square problem. This classification is obtained bycomparing the pulse signature with the reference dictionary to find a set thatmost closely matches the pulse features. This work also sheds additional lighton the possibility of fault classification based on the pulse signature. Fielddata collected from a distribution system are used to verify the effectivenessand reliability of the proposed method.
