Abstract

EL INVENTO SE REFIERE A UN CIRCUITO DE ENTRADA PARA UN CONTADOR DE ENERGIA ELECTRICA (CE), CONSTANDO DICHO CIRCUITO DE UNA VIA DE CORRIENTE (WI) Y UNA VIA DE TENSION (WU), ESTANDO ASOCIADA LA VIA DE CORRIENTE A UN TRANSFORMADOR DE INDUCTANCIA MUTUA (CAI). PARA COMPENSAR LA FUNCION DERIVADORA DEL TRANSFORMADOR SIN INTRODUCIR SEÑALES PARASITAS, LA VIA DE CORRIENTE CONSTA DE UN FILTRO ACTIVO A, R1, C1 MONTADO EN INTEGRADOR AUNQUE DOTADO DE UNA CAPACIDAD DE ACOPLAMIENTO C2 APTA PARA BLOQUEAR LAS SEÑALES DE BAJA FRECUENCIA.
