Abstract

Patente de Invenção: <B>"PROCESSO E DISPOSITIVO PARA O MONITORAMENTO ELéTRICO DE UMA LINHA DE ELETRODOS DE UMA INSTALAçãO DE TRANSMISSãO DE CORRENTE CONTìNUA DE ALTA-TENSãO BIPOLAR"<D>. Para o monitoramento de uma linha de eletrodos (4) composta por duas linhas (20, 22), de uma instalação bipolar HGu, a partir de um pulso assimétrico quanto à terra (u (t)) introduz-se um pulso simétrico quanto à terra, no modo vaivém, nas linhas (20, 22) e a partir dos sinais de eco registra-se uma curva de eco efetiva (EK), a qual é comparada com uma curva de eco teórica dinâmica, sendo que, no caso de ultrapassagem de uma faixa de tolerância disposta em torno da curva diferencial de eco (EDK), é gerado um sinal de defeito. Com isso, obtém-se um processo de monitoramento que é aproximadamente independente da condutibilidade de terra intensamente oscilante, que apresenta um maior alcance acompanhado de uma menor dispersão simultânea de eco, e que irradia uma menor energia eletromagnética, assim como não requer nenhum elemento adicional de desacoplamento.
