Abstract :
This paper describes how to precisely coordinate distribution feeder automatic-circuit reclosers using cooling-factor data that accounts for the heating and cooling of the source-side fuse that occurs during the recloser´s operating sequence. This method yields results that are more accurate than other coordination methods commonly employed. Different coordination methods are discussed in this paper and the results are compared
