국내환경을 고려한 IEC 60364 기반 차단기 동작 특성 연구

This Paper present about Circuit breaker Operating time in 220 V when ground fault occur Analysis parameters were touch voltage, electrical shock current and human body resistance. Result. Circuit Breaker operating time establish for keep away electrical shock & prevention electrical accident of a equipment. So Circuit Breaker operating time was 0.4 s in 220 V.
