Abstract (en)

[origin: FR2756051A1] The invention concerns a method for the automatic analysis of faults on a network, characterised in that it comprises steps consisting in: breaking down the electric signals measured on the network, into electric loads each corresponding to a portion of time during which the measured signals are stable or quasi-stable, on the basis of a self-adapted quiescent value by statistical analysis of said signals, and detecting each faulty leading-in and each faulty output on each of the detected phenomena.
