Abstract

RELÉ DE PROTEÇÃO PARA PROTEÇÃO SENSÍVEL DE FALHA À TERRA. A presente invenção refere-se ao projeto do aspecto de proteção em um relé de proteção autoalimentado. A invenção apresenta especificamente um relé com proteção de falha à terra sensível. Essa proteção é atingida em série com tempo ótimo de disparo com energia ligada (comutação para falha) e com lógica integrada para discriminação da irrupção. O relé de proteção autoalimentado é dotado com um módulo de processamento de corrente adaptado para medir e avaliar a corrente da linha para gerar o sinal de disparo. O módulo de processamento da corrente tem a capacidade de supressão da corrente da irrupção para bloquear a detecção da falha à terra durante uma condição de irrupção e dessa maneira aumentar a sensibilidade da detecção da falha.
