Abstract
"SISTEMA PARA COMUNICAR INFORMAçãO ATRAVéS DE UMA LINHA DE COMUNICAçãO QUE CONECTA PELO MENOS DOIS RELéS PROTETORES PARA UMA LINHA DE ENERGIA ELéTRICA". O sistema provê comunicação de informação entre pelo menos dois relés protetores (10,12) servindo uma linha de sistema de potência (14). A comunicação inclui uma série de mensagens de dados sucessivas de quatro caracteres, cada uma das quais inclui oito bits de dados, em oito canais de dados. Os bits de dados incluem bits de estado de função de saída do relé de transmissão (10) em canais selecionados por usuário, e bits de dados de terminal virtual em ainda outros canais selecionados por usuário. Um canal de sincronização (30) produz informação para sincronizar a transmissão/recepção dos dados analógicos e dos dados de terminal virtual, na base de quadros de dados, cada quadro contendo 18 mensagens.
