SECTIONALIZING AND FUSING STUDIES
Sectionalizing: Proper sectionalizing of a distribution system can have a considerable effect on continuity of service and overall system reliability. Strategic placement and coordination of protective devices (breakers, fuses, sectionalizers, etc.) can limit fault-induced service interruptions to the fewest possible customers and the shortest possible time. Proper sectionalizing will protect the distribution circuit and associated equipment by providing desired responses to different types of faults.
An arc-flash assessment is performed to determine the level of threat the electric system presents to utility workers, property and the general public in the event of an unplanned arc-flash (or, flashover) of a system component or components. The assessment identifies risk level s using a system of metrics which differentiates high, low and average risk locations across the service area. Arc-flash assessment and mitigation planning are now mandated by all major national safety codes, including NEC, NESC and OSHA, as well as State and local codes and standards. Since an accurate model of the electric system (including properly-modelled sectionalizing and fault-clearing devices) is important for a successful arc-flash study, the arc-flash study is a natural extension to a sectionalizing study and can be merged into one efficient and cost-effective study activity.
