Abstract

This study provides review and improvement plans for the possible problems caused when the CV cable is used as a positive feeder line which supplies power from the DC HSCB (high-speed circuit breaker) to the catenariesin Seoul Metro which is using direct-current feeder method. In detail, this study contributes to stabilizing the power line by triggering a protective device by instantly detecting potential rise which happens when grounding fault occurs in non-grounding type CV cable shield.
