Abstract
SISTEMA DE TRANSMISION EN BUCLE PARA CONTROLAR SU CONDICION DE RETORNO, DEL TIPO QUE COMPRENDE UNA SERIE DE ESTACIONES NODALES, UNA ESTACION SUPERVISORA Y LINEAS DUPLICADAS DE TRANSMISION EN BUCLE, POR LAS CUALES TRANSMITE SEN/ALES EN DIRECCIONES OPUESTAS.CARACTERIZADO PORQUE LA ESTACION SUPERVISORA TRANSMITE ORDENES DE RETORNO A AMBAS LINEAS DUPLICADAS DE TRANSMISION EN BUCLE AL MISMO TIEMPO; PORQUE CADA UNA DE LAS ESTACIONES NODALES ESTABLECE UNA VIA DE RETORNO MIENTRAS CONSERVA UNA VIA DE CONEXION A UNA ESTACION NODAL SUCESIVA AL RECIBIR UNA ORDEN DE RETORNO; Y PORQUE LA VIA DE RETORNO QUEDA LIBRE UNICAMENTE EN LAS ESTACIONES NODALES.
