Abstract

Procedimiento para la determinación de la duración de servicio restante de los contactos de conmutación de un dispositivo de conmutación eléctrico, especialmente dispositivo de conmutación de baja tensión, caracterizado porque - se captan las señales sonoras propagadas por estructuras sólidas generadas por el proceso de conmutación, - las señales sonoras propagadas por estructuras sólidas captadas para la captación del sonograma se someten en diferentes ventanas de tiempo a una transformación de Fourier, y - se determinan los valores de funciones individuales captadas del sonograma y se evalúan mediante un dispositivo de evaluación.
