Abstract

SISTEMA E MéTODO PARA MONITORAMENTO DE IMPEDáNCIA. A presente invenção refere-se a um sistema (10) para monitorar impedância PLC de um condutor de fase 12.1 de uma linha de transmissão de energia de alta voltagem suspensa (OHTL) 12 compreende um híbrido 40 que compreende uma primeira porta (40), uma segunda porta (40,2) e uma terceira porta (40,3). O híbrido é configurado para dividir energia recebida na primeira porta entre as segunda e terceira portas, no mínimo parcialmente para isolar a segunada porta de energia recebida na terceira porta e, no mínimo parcialmente, para isolar a terceira porta de energia recebida na segunda porta. O isolamento é uma função de uma impedância conectada à primeira porta 40.1. A primeira porta é conectada ao condutor de fase. A segunda porta é conectada para ser acionada por uma fonte de sinal alternante (14). As segunda e terceira portas são conectadas a um dispositivo de registro de monitoramento (42) para moniotrar sinais nas segunadas e terceira portas, com isto, para monitorar o isolamento nas segunda e terceira portas e daí, impedância na primeira porta.
