The Field Test of Feeder Automation using Fault Indicator having the information of fault current flowing

고장전류 통전정보를 갖는 Fault Indicator를 이용한 선로자동화 실증시험

For feeder automation function, we must have Fault Indicator with the information of fault current flowing inside automatic feeder switches. In this paper, we introduce the algorithm of feeder automation, the theory of fault indicator, the result with some troubles of field test in real distribution system and contents of improvement.
