Abstract

A FIN DE QUE UN CONTADOR DE ELECTRICIDAD (1) PUEDA CONTROLAR DE MANERA EXHAUSTIVA SUS PROPIOS CANALES DE MEDICION, LA INVENCION PREVE QUE LAS SEÑALES DE ENTRADA, EN ESPECIAL LAS SEÑALES DE CORRIENTE Y DE INTENSIDAD (I1 A I3, O BIEN U1 A U3), SE SOMETAN A UN DOBLE PROCESO DE DETECCION MEDIANTE DIFERENTES CANALES DE SEÑAL (3A A 3C) CON MODULADORES SIGMA-DELTA (15A A 15C). UNA UNIDAD DIGITAL DE PROCESO DE SEÑAL (5) SITUADA A CONTINUACION COMPRUEBA LA PLAUSIBILIDAD DE LAS SEÑALES DETECTADAS (I1 A I3, O BIEN U1 A U3), GENERANDO UNA SEÑAL DE ERROR EN FUNCION DEL TIPO DE ERROR O DESVIACION DE LA SEÑAL.
