Improved distribution system reliability at Northeast Utilities: a case history

Significant improvements in distribution service reliability through the use of automated reclosers in an interactive network, identified as a loop scheme, are documented. The case study covers system design, control equipment design, reliability considerations, control types and application, and performance results. An understanding of various loop schemes is included, for both new and existing distribution feeder sectionalizing. Possible future developments offering further distribution system reliability improvements are noted
