Abstract

sistema de proteção, método para operar um sistema de proteção e sistema de circuito trata-se de um sistema de proteção que inclui um módulo de controle, um comutador e um dispositivo indutivo. o módulo de controle é usado para fornecer sinais de controle e sinais de comutação com base, pelo menos em parte, em um sinal detectado medido por um dispositivo de detecção. os sinais de controle incluem um primeiro sinal de controle correspondente a um modo normal e um segundo sinal de controle correspondente a um modo de falha. o comutador é ligado e desligado de acordo com os sinais de comutação. o dispositivo indutivo é acoplado ao comutador. o dispositivo indutivo é controlado para ser operado com uma primeira indutância em resposta ao primeiro sinal de controle fornecido a partir do módulo de controle e uma segunda indutância em resposta ao segundo sinal de controle fornecido a partir do módulo de controle. um método para operar o sistema de proteção e um sistema de circuito com base no sistema de proteção também são fornecidos.
