Abstract
DETECTOR DIGITAL DE SECUENCIA DE FASE PARA UN RELEVADOR PROTECTOR DE VIGILANCIA EN LINEAS DE TRANSMISION DE ENERGIA ELECTRICA. CONSTA DE DOS CIRCUITOS (14 Y 20) PARA CONVERTIR EN CUADRADAS LAS ONDAS SENOIDALES DE DOS FUENTES DE FASORES (12 Y 18); DE UN ELEMENTO (70) QUE DIVIDE UNA DE ESTAS ONDAS (VP) EN OTRAS DOS; Y DE UNA SERIE DE CIRCUITOS (24, 26, 28 Y 72) CONSTRUIDOS A BASE DE PUERTAS LOGICAS E INTERCONECTADOS DE TAL FORMA QUE EN LA SALIDA (Z ELEVADO ,) DEL DETECTOR SE PRODUCE UN CAMBIO DE ESTADO CUANDO LOS FASORES INTERCAMBIAN POSICONES ADELANTADAS Y RETRASADAS. EL CAMBIO DE ESTADO PERSISTE MIENTRAS LO HACE LA NUEVA RELACION DE LOS FASORES.
