Abstract

"DETECTOR E MéTODO PARA DETECTAR FALHAS POR ARCO PARA UM SISTEMA DE ENERGIA ELéTRICA CA E DISJUNTOR DE FALHA POR ARCO PARA UM SISTEMA ELéTRICO DE 400 HZ". A invenção divulga um detector de falha por arco para sistemas de energia elétrica CA em geral e é particularmente adequada para um sistema elétrico CA de aeronave ou outros sistemas CA operando em freq³ências mais altas tais como 400 Hz. O detector de falha por arco da invenção inclui um detector de corrente detectando a corrente CA fluindo no circuito elétrico, e um processador que gera uma soma cumulativa de quantidades pelas quais a corrente CA em cada intervalo cíclico o mais recente excede a corrente no meio ciclo imediatamente precedente em magnitude absoluta. Uma indicação de falha por arco é gerada quando esta soma cumulativa alcança um nível selecionado. A invenção também abrange um disjuntor incorporando o detector de falha por arco descrito acima. Ela adicionalmente inclui um método para detecção de falha por arco.
