Abstract

반복사이클을 제공하는 소정의 주파수의 AC전원(26)으로부터 부하(30,31)에 AC라인 전류를 공급하는 전기회로에서, AC라인전류의 사이클대 사이클 변화를 감지하므로서 아크검출이 제공된다. AC라인전류는 AC전원(26)의 다수의 각각 m 사이클동안 조화노치필터(72)에 의해 다수의 n 위상(θ1∼θn)으로 샘플되어 다수의 전류(In,m)을 제공한다. 여기서, n은 위상, m은 사이클이다. 차이(In,m)-(In,m-x)(여기서 x는 사이클의 지정 번호)는 다수의 전류차동신호를 제공한다. 이 전류차동신호(ID)의 절대값은 m사이클에 대해 동기화 합산기(94)에 누적된다. 아크표시신호는 누적절대 전류차동신호(ID)의 상태(116)의 소정의 결합 및 소정의 상태에 따라 발생된다. AC라인 전압의 사이클대 사이클은 조화노치필터(146)로 감지되고, 표시신호가 소정의 전압상대에 따라 디스아암된다. 또 다른 실시예에서 서브사이클 변화가 감지된다.
