Abstract
<B>"DISPOSITIVO PARA DETECTAR DESCARGAS ELéTRICAS EM UM OBJETIVO DE TESTE, PREFERENCIALMENTE UMA JUNTA DE CABO"<D>. Um dispositivo para detectar descargas elétricas em um objeto de teste (1) com dois condutores de conexão elétrica (1a, 1b, 1c, 1d), preferencialmente uma junta de cabo, compreende pelo menos um primeiro e um segundo sensor (2a, 2b) e um equipamento de avaliação (EVU). Cada um dos sensores gera a fornecer ao equipamento de avaliação sinais sensores na dependência de pulsos de corrente através dos condutores de conexão e na direção dos mesmos, o primeiro sensor um primeiro sinal sensor (v1) e o segundo sensor um segundo sinal sensor (v2). O equipamento de avaliação gera na dependência dos sinais sensores recebidos, um sinal de indicação (IND), que indica uma descarga elétrica no objeto de teste. O dispositivo compreende uma primeira unidade de sintonização (T1) associada ao primeiro sensor e uma segunda unidade de sintonização (T2) associada ao segundo sensor, cada unidade, na dependência do respectivo sinal sensor, formado um primeiro sinal de filtro (SF1) e um segundo sinal de filtro (SF2), respectivamente, periodicamente oscilando em um período pré-selecionado (TP), assim como um elemento de multiplicação (MU) que é fornecido com e na pendência dos ditos sinais de filtro, formando um sinal de produto (SP), pelo que o equipamento de avaliação forma o sinal de indicação na dependência do sinal de produto.
