Abstract: The invention concerns a sensor simulation system. The simulation system (1) comprises a generator (3) that generates a digital signal by direct digital frequency synthesis, based on the following parameters: a frequency, an amplitude, a phase and amplitude shift; a digital/analog converter (4), and a means (6) that modulates the signal received from said converter (4).

Abstract: A method and device for detecting an electrical arcing phenomenon operate to measure an electric current and an electric voltage on an electric cable. The measurements are filtered and the filtered measurements are digitized to produce two digitized data segments. Each of the two segments is subjected to a number of functions to produce a form vector. The membership class of the form vector is determined, and the presence or absence of an electric arcing phenomenon is determined from the membership class.
