Abstract

ANTENA DE DETECÇÃO DE ARCO EM SISTEMAS DE MEDIDOR ELÉTRICO. Trata-se de um medidor elétrico em uma caixa de serviço público que é capaz de detectar condições de formação de arco entre lâminas de medidor e um soquete de medidor na caixa de serviço público em instalações. O medidor elétrico inclui uma estrutura de transformador de corrente que forma um espaço fechado. Uma antena de detecção de arco pode ser posicionada no espaço fechado em conjunto com o transformador de corrente. A estrutura de transformador de corrente é posicionada em uma placa de base do medidor elétrico próximo às lâminas conectadas ao soquete de medidor. Os fios terminais da antena de detecção de arco são conectados eletricamente a um circuito de detecção de arco configurado para detectar condições de formação de arco com base no sinal recebido da antena de detecção de arco. Caso seja determinado que a condição de formação de está presente, o medidor elétrico pode ser ativado para interromper a conexão entre a fonte de alimentação e as instalações.
