Abstract

"APARELHO AUTO-ENERGIZáVEL E MéTODO PARA DETECTAR OPTICAMENTE FALHAS DE ARCO EM SISTEMAS DE ENERGIA ELéTRICA NA PRESENçA DE OUTRAS FONTES DE LUZ". Falhas de arco em um sistema de energia elétrica são detectadas por sensores (1, 11) energizados pela luz gerada pela formação de arco mesmo na presença de luz de fundo. Os sensores (1, 11) têm uma ou mais células fotovoltaicas (5) energizadas pela luz passada através de um primeiro filtro (7) tendo uma banda de passagem a qual inclui um comprimento de onda característico do material de formação de arco para gerar um sinal elétrico de luz detectada. Uma ou mais segundas células fotovoltaicas (11) são energizadas por luz filtrada por um segundo filtro (13) tendo uma banda de passagem não incluindo o comprimento de onda característico para gerar um sinal elétrico de luz de fundo. Estes dois sinais elétricos são aplicados em oposição a um LED (17) o qual é ligado quando formação de arco está presente. O sinal de luz a partir do LED (17) é transmitido através de uma fibra ótica (29) para um circuito fotoelétrico (25), o qual gera um sinal de formação de arco quando energizado. O LED (17) pode ser forçado para a condição ligado por células fotovoltaicas não filtradas adicionais (21).
