Switching Characteristics of a Superconducting Current Limiter

According to the rapid growth of transmission power, fault current level approaches to the maximum capacity of circuit breaker. This paper has been proposed a superconducting current limiter (SCL) to reduce the fault current to appropriate level. Superconductor for SCL has been examined and design criterion of each triggering method has been shown. Superconducting current limiter was fabricated using thin film and switching characteristics were shown, where thermal and current triggering were adopted.
