Abstract

1 / 1 resumo “aparelho e mã‰todo para detecã‡ãƒo da descarga parcialâ€� aparelho para detecã§ã£o da descarga parcial (500), compreendendo: uma estrutura de suporte (3); uma primeira antena (1) configurada para receber sinais eletromagnã©ticos (s ) pelo menos d parcialmente associados com as descargas parciais de um objeto elã©trico (100) e para gerar um primeiro sinal elã©trico (s ); tendo a primeira antena uma entrada1 primeira ã¡rea receptora efetiva para as primeiras direã§ãµes de recepã§ã£o e uma segunda antena (2) configurada para receber sinais de ruã­dos eletromagnã©ticos (s ) e para gerar um segundo sinal elã©trico (s ); sendo a primeira e a r entrada2 segunda antenas arranjadas de modo a fazer com que a segunda antena tenha uma segunda ã¡rea receptora efetiva, para as ditas primeiras direã§ãµes de recepã§ã£o, menor do que a dita primeira ã¡rea receptora efetiva. o aparelho inclui adicionalmente um primeiro mã³dulo de processamento (600) configurado para gerar, a partir dos ditos primeiro e segundo sinais elã©tricos, um sinal elã©trico da diferenã§a (s ), que representa a diferenã§a entre o saã­da primeiro sinal elã©trico e o segundo sinal elã©trico.
