Analysis of Active Characteristic the Low-voltage Circuit Breaker for Harmonics

고조파에 의한 저압용 차단기의 동작특성 해석

Because MCCB, ELB, etc. discharge both technical and economical duty, it is important that the study of circuit breaker guarantee high-performance and realize the power distribution system with reliability. Because of complexity electrical equipment, the accident with imbalance and flicker occur often according to technical improvement. However, study of accident with harmonics remains. In this paper, the essential characteristic of circuit breaker is introduced. To analysis operation of circuit breaker, theoretical model and several simulations have been performed.
