Abstract

DURANTE LA CONDUCCION DE LA CARGA (A,B) LA INTENSIDAD DE CORRIENTE Y EL VOLTAJE PRESENTES EN ESTA SON MONITORIZADOS (9A, 9B) POR COMPARACION DE SUS CALORES CON EL UMBRAL DE CORRIENTE Y CON UNA VENTANA DE CALORES DE VOLTAJE PERMISIBLES. CUANDO EL VOLTAJE ESTA FUERA DE LOS VALORES PERMISIBLES Y/O LA CORRIENTE DESCIENDE POR DEBAJO DE SU UMBRAL UN MENSAJE DE FALLO (FAULT) Y LA NATURALEZA DEL FALLO (CORTOCIRCUITO EN EL NUCLEO, CARGA ABIERTA, CORTO CIRCUITO EN LA TENSION DE LA RED DE DISTRIBUCION), ES TAMBIEN IDENTIFICADO POR LA EMISION DE UNA SEÑAL CORRESPONDIENTE DE UN DIAGNOSTICO NATICO (DIAGA, DIAGB). LA IDENTIFICACION (STAGE) DE LA FASE O FASES DEL FALLO ESTA TAMBIEN PROVITA EN EL CASO DE CIRCUITO QUE INCLUYE VARIAS FASES EN PARALELO. LA APLICACION REFERIDA ESTA DESTINADA A LA CONDUCCION DE LA INYECCION EN MOTORES DE COMBUSTION INTERNA.
