摘要
A time-current coordination (TCC) curve for a programmable low-set instantaneous overcurrent (IOC) relay for at least one station breaker in an electrical distribution feeder with a fuse-saving scheme and a method of coordinating at least one recloser with the station breaker in the said feeder, for the reduction of frequency of power interruptions encountered by at least one load on the feeder and wherein the method includes the steps of: (a) feasible selection of a range for a time delay of a station breaker's programmable low-set IOC relay; (b) choosing a time delay based on a fuse-saving relation; and optionally (c) locating the recloser on the feeder.
