Abstract

"DETECTOR DE FALHA DE CORRENTE E INTERRUPTOR DE CIRCUITO E ACONDICIONAMENTO PARA O MESMO". A invenção refere-se a um controlador de energia posicionado em um percurso de corrente entre o lado da linha e o lado da carga de um circuito elétrico. O controlador de corrente fecha o percurso de corrente na presença de um suprimento de controle e abre o percurso de corrente na ausência do suprimento de controle. Um suprimento de energia eletricamente conectado no percurso de corrente provê o suprimento de controle. Um sistema de sensor recebe energia do suprimento de energia, monitora a corrente no percurso de corrente e emite um sinal de sensor indicativo de uma condição de corrente no percurso de corrente. Um controlador lógico também recebe energia do suprimento de energia, recebe o sinal de sensor e remove o suprimento de controle do controlador de energia quando o sinal de sensor não satisfaz um critério estabelecido. O sistema de sensor pode incluir um ou ambos de um sensor de desequilíbrio para monitorar o equilíbrio de corrente entre duas ou mais linhas elétricas e sensores de sobrecorrente para monitorar a corrente nas linhas individuais.
