Abstract

EL SISTEMA DE PROTECCION Y TELEALIMENTACION ASI COMO EL DISPOSITIVO EXTRACTOR DE TELEALIMENTACION SE DESTINAN A UN EQUIPAMIENTO CONECTADO POR DOS TRANSFORMADORES (9, 10) A UNA UNION DE TRANSMISION (1) CON DOS PARES DE HILOS QUE ASEGURAN LA TELEALIMENTACION DEL EQUIPAMIENTO. CADA TRANSFORMADOR ESTA ENLAZADO A LO DOS HILOS DE UN PAR (2 O 3) POR DOS ENROLLAMIENTOS IDENTICOS (13, 14 O 15, 16) CONECTADOS EN SERIE ENTRE ESTOS DOS HILOS A TRAVES DE UN CONDENSADOR (15 O 18). LOS DOS PARES DE HILOS CONSTITUYEN UN CIRCUITO DE ALIMENTACION FANTASMA, LOS DOS HILOS DE UN MISMO PAR ESTAN UNIDOS AL MISMO BORNE DE UN GENERADOR DE CORRIENTE CONTINUA (27). EL DISPOSITIVO DE PROTECCION Y EXTRACCION COMPORTA DOS PUENTES CORRECTORES (28, 29) SEPARADAMENTE UNIDOS POR SUS ENTRADAS CADA UNO A UN PAR DE HILOS E INTERCONECTADOS POR SUS SALIDAD PARA FACILITAR LA TELEALIMENTACION.
