Abstract
EL DISPOSITIVO DE MEMORIZACION COMPRENDE UN CIRCUITO (11) QUE COMPRENDE UNA RESISTENCIA (RM), UN CONDENSADOR (CM) Y UN DIODO (DM). EL CONDENSADOR (CM) ESTA CARGADO POR UNA CORRIENTE FUERTE (IH), PARA LA MEMORIZACION DE UN DEFECTO TERMICO ANTES DEL DISPARO. A CONTINUACION, EL CONDENSADOR SE DESCARGA EN LA RESISTENCIA. Y DURANTE EL DISPARO, LA CARGA DEL CONDENSADOR SE DETERMINA INYECTANDO UNA CORRIENTE DEBIL (IB) Y COMPARANDO LA TENSION (VM) EN LOS BORNES DEL CIRCUITO (11)( CON UN UMBRAL (VS). EL RESULTADO DE ESTA COMPARACION PERMITE INICIALIZAR UNA MAGNITUD REPRESENTATIVA DEL ESTADO TERMICO DE UNA RED A PROTEGER. ESTE DISPOSITIVO PUEDE APLICARSE PARTICULARMENTE A LOS DISYUNTORES O A LAS PROTECCIONES DE LOS MOTORES ELECTRICOS.
