Coordination of protective devices
Web•Protection coordination is also handled through dividing the power system into protective zones. •If a fault were to occur in a given zone, necessary actions will be executed to … WebA coordination study is an organized effort to achieve optimum electrical distribution system protection by determining the appropriate frame sizes, ampere ratings and settings of overcurrent protective devices. When an overcurrent occurs in a properly coordinated distribution system, only the protective device nearest the fault will open.
