Abstract
Aparato de vigilancia para mantener una potencia máxima media en una instalación eléctrica, caracterizado por un dispositivo para la producción de una tensión rectificada proporcional de potencia que se transforma por medio de un transformador de tensión-frecuencia, en una frecuencia proporcional de potencia, sumándose los impulsos de esta frecuencia durante un intervalo entre dos impulsos de ciclo y poniendo un biestable al sobrepasar de un valor limite cuyo estado llega a un registro corredera cuyo conteniendo es valorado después de cada impulso de ciclo; y un circuito lógico que desconecta los consumidores o grupos de consumidores vigilados respectivamente al sobrepasar un valor del contenido del registro corredera según prioridades programadas, y mas tarde los añade otra vez conectándolos.
