Abstract

PURPOSE: To permit protection according to load characteristics to be made for each feeder line by providing sensors for detection items corresponding to respective protection ends on individual load feeder lines.
CONSTITUTION: A plurality of circuit protection sensors for detection items corresponding to respective protection ends such as current leak, overload, short-circuit, overvoltage and so forth are provided on respective load feeder lines a to c branching from a trunk feeder line M for operating a breaker B on the trunk feeder line M with the output signal from each sensor. Since the sensors for different detection items corresponding to respective protection ends are provided on the respective load feeder lines, it is possible to obtain sofisticated and reliable protection according to the characteristics of the load for each load feeder line. Also, no breaker is provided on each load feeder, which is economical.
