Abstract
ERGOMETRO DE ALTA PRECISION CAPAZ DE MEDIR LA CORRIENTE SUMINISTRADA O CONSUMIDA EN LAS MULTIPLES FASES DE UN SISTEMA DE DISTRIBUCION, Y QUE ESTA CONSTRUIDO COMO CIRCUITO INTEGRADO. UNOS TRANSDUCTORES DETECTORES DE VOLTAJE Y CORRIENTE ACOPLADOS AL ERGOMETRO PROPORCIONAN SEÑALES DE ENTRADA CON UN POTENCIAL PROPORCIONAL AL VOLTAJE Y LA CORRIENTE EN EL SISTEMA DE DISTRIBUCION. UN MULTIPLICADOR DE INYECCION DE LA AMPLITUD DEL ANCHO DEL IMPULSO DE CARGA BAJA, QUE UTILIZA UNA ONDA TRIANGULAR SINTETIZADA DIGITALMENTE, EXISTE EN CADA FASE. CADA MULTIPLICADOR RECIBE LAS SEÑALES DE ENTRADA Y PROPORCIONA UNA SEÑAL DE SALIDA DE CORRIENTE PROPORCIONAL AL PRODUCTO DEL VOLTAJE Y LA CORRIENTE EN ESA FASE DEL SISTEMA DE DISTRIBUCION. LA CARGA DE LAS CORRIENTES DE SALIDA DEL MULTIPLICADOR PARA TODAS LAS FASES SE ACUMULA EN UN CAPACITOR CONECTADO A TRAVES DE UN AMPLIFICADOR AUTORREINICIALIZADOR QUE CORRIGE SU PROPIA DESVIACION DE VOLTAJE. LA SALIDA DEL AMPLIFICADOR CONTROLA UN CONMUTADOR CONECTADO ENTRE UN POTENCIAL DE REFERENCIA Y EL CAPACITOR. CUANDO EL CONMUTADOR ESTA CERRADO UNA CORRIENTE DE REFERENCIA PASA AL CAPACITOR ACUMULADOR PARA EQUILIBRAR LA CARGA DEL MULTIPLICADOR PARA CADA FASE. LA FRECUENCIA DE LA SEÑAL DE CONTROL DEL CONMUTADOR PROPORCIONA UNA MEDIDA MUY PRECISA DE LA CORRIENTE CONSUMIDA O SUMINISTRADA POR EL SISTEMA DE DISTRIBUCION.
