Abstract

EN UN DISPOSITIVO QUE SIRVE PARA EL CONTROL DE CORRIENTE DE VARIAS FASES Y QUE DA UNA SEÑAL SEGURA CON RESPECTO A TODAS LAS FASES (R, S, T) DEL SISTEMA AL MISMO TIEMPO QUE AL VALOR MEDIO REFERIDO, Y TAMBIEN AL PASO MINIMO DEL VALOR DE DESCONEXION (MAS PEQUEÑO QUE 10%) Y DE MENOR TIEMPO (MENOR QUE 0,1 SEGUNDOS), SE ACONSEJA QUE SE UTILICE UN RELE MAGNETICO, QUE ALCANCE LA INDEPENDENCIA DE CORRIENTE DEL MOMENTO MEDIANTE INTERFERENCIAS ADITIVAS QUE DE CADA UNA DE LAS FASES GENERA UNA FUERZA MAGNETICA (F SUB R, F SUB S, F SUB T).
