초전도전류생성기의 스위칭 특성
Switching Characteristics of a Superconducting Current Limiter
초록
With the rapid growth of power system capacity, fault current levels approach the maximum capacity of circuit breakers. In this paper, a superconducting current limiter (SCL) is proposed to reduce the fault current to an appropriate level. Superconductor for SCL has been examined and design criterion of each triggering method has been shown. Thin film SCL has been fabricated and switching characteristics are shown, where thermal and current triggering methods are adopted. Experimental result shows that fault current is reduced to one-half.
