Abstract

SISTEMA DE MONITORAMENTO PARA AVALIAÇÃO DE UMA CONDIÇÃO DE UMA REDE ELÉTRICA. Trata-se, em geral, de um sistema de monitoramento que inclui um ou mais nós que são capacitivamente acoplados a um cabo de uma linha de transmissão de energia elétrica multifásica. Em alguns exemplos, um nó inclui uma camada de acoplamento disposta sobre uma camada de invólucro do cabo e capacitivamente acoplada a uma camada de blindagem do cabo. Em alguns exemplos, um nó pode incluir uma primeira camada de acoplamento capacitivamente acoplada a um primeiro cabo, e uma segunda camada de acoplamento capacitivamente acoplada a um segundo cabo, de modo que o nó seja diferencialmente acoplado ao par de cabos para gerar um sinal de dados diferencial e para executar pelo menos um dentre: detectar um sinal nativo dentro do par de cabos; injetar um sinal intencional no par de cabos; receber um sinal intencional de dentro do par de cabos; ou fornecer uma caracterização de canal.
