Coordination of relays, reclosers, and sectionalizing fuses for overhead lines in the oil patch

摘要

The authors cover certain generalities and fundamentals of oil-patch distribution system coordination, and identify some of the specific items of analysis to be concerned with. Some concepts are proposed for solutions to the problems of obtaining protective device coordination between sectionalizing fuses, line reclosers, and feeder breakers, especially as related to upgrading existing substation and feeder line protection on medium-voltage power systems.
