Abstract

A FIN DE MEJORAR EL PROCESAMIENTO DE SEÑALES EN UN CONTADOR DE ELECTRICIDAD (E1, E2, E3, E4) CON TRANSFORMADORES DE ENTRADA DIFERENCIADORES (W1, W2, W3, WI), ESPECIALMENTE TRANSFORMADORES DE CORRIENTE, SE INSTALA UN FILTRO ANALOGICO, ESPECIALMENTE UN FILTRO DE PASO BAJO, CORRIENTE ABAJO DE LOS TRANSFORMADORES DE ENTRADA. DE ESTE MODO SE LIMITAN LOS PICOS DE VOLTAJE PARA LOS COMPONENTES ELECTRONICOS SITUADOS CORRIENTE ABAJO. LAS ALTERACIONES DE LAS SEÑALES MEDIDAS PROVOCADAS POR LOS FILTROS SE COMPENSAN POR MEDIO DE UN FILTRO DIGITAL DURANTE EL PROCESAMIENTO DE SEÑALES POSTERIOR.
