Abstract

UN MONITOR QUE DETECTA PUNTOS CALIENTES DEL NUCLEO DE UN GENERADOR (12) DONDE EL AISLAMIENTO ENTRE LAS CHAPAS MAGNETICAS ESTA SIENDO PERFORADO EN BASE A CHEQUEAR LAS TENSIONES DIFERENCIALES EN CADA EXTREMO DEL EJE ROTOR (14) PARA PRODUCIR UNA SEÑAL DE VOLTAJE QUE VARIA POR DEFECTOS FUNCIONALES EN EL NUCLEO (12). COMPARANDO MUESTRAS DE ESA SEÑAL A LO LARGO DEL TIEMPO, PUEDE SER DETECTADO EL DEFECTO DEL NUCLEO.
