Abstract
The method involves taking up an electrical system voltage and evaluating the ripples of the electrical system voltage in order to determine a generator defect. The electrical system voltage or a signal derived from it, concerns the amplitude or the frequency of the signal. A comparison is made against a threshold value : An independent claim is included for a device.
