Abstract
La presente invención se refiere a un sistema de calibración para medición de energía mejorado, para un medidor de electricidad del tipo que consiste de un circuito de procesamiento de señales para determinar los parémetros de uso de energía de línea haciendo medidas de corriente y voltaje de línea de energía, y, en respuesta obteniendo una señal de salida relacionada con los parámetros de energía, en donde los errores tienden a quedar contenidos en la señal de salida como resultado de los errores de ganancia, fase y de descentrado distribuidos dentro del circuito de procesamiento de señales, en donde la mejora consiste de: (a) una pluralidad de resistencias interconectadas; (b) una pluralidad de interruptores eléctricamente controlados que se interconectan con la plurarlidad de resistencias para formar una red divisora de voltaje variable que tiene valores del divisor de voltaje de salida que dependen de los estados de "conexión" y "desconexión" de los interruptores; (c) un elemento para obtener una salida de la señal desde la red divisora de voltaje que es representativa de la calibración requerida para corregir uno de los errores, y (d) un elemeto para conectar la salida de la señal desde una red divisora de voltaje variable con el circuito de procesamiento de señales a fin de corregir uno de los errores, calibrando de esta manera el circuito.
