Abstract

La presente invencion se refiere a un sistema que proporciona comunicacion de informacion entre al menos dos relevadores protectores (10, 12) que sirve a una linea (14) del sistema de energia. La comunicacion comprende una serie de mensajes de datos sucesivos de 4 caracteres, cada uno de los cuales incluye ocho bits de datos sobre ocho canales de datos. Los bits de datos incluyen bits del estado de la funcion de salida del relevador (10) de transmision sobre canales seleccionados del usuario y bits de datos de terminal virtual sobre todavia otros canales seleccionados del usuario. Un canal (30) de sincronizacion produce informacion para sincronizar la transmision/recepcion de los datos analogicos y los datos de la terminal virtual, en base a marcos de datos, cada marco contiene 18 mensajes.
