Abstract
Patente de Invenção: <B>"DETECçãO DE FALHAS SUBCICLO AUTOCORRIGIDAS"<D>. é apresentado um aparelho que detecta falhas autocorrigidas em um circuito elétrico de CA conduzindo uma corrente elétrica. Para este fim, o aparelho inclui um elemento rápido que detectar uma ocorrência de uma falha dentro de um ciclo de iniciação, detecta uma correção da falha dentro de um ciclo da correção, e detecta uma duração da falha dentro de um ciclo ou menos. O aparelho adicionalmente inclui um elemento de auto-correção que compara a duração da falha com uma parte predeterminada de um ciclo da corrente elétrica para determinar se a falha é de correção automática.
