DC철도 급전계통 보호시스템 구성
A Protection Scheme for DC Railway Systems
초록
A DC railway system has low feeder voltage, The fault current can be smaller than the current of load starting. So it is important to discriminate between the small fault current and the load starting current. The load starting current increases step by step but the fault current increases all at once. So the type of
