Beschreibung
Zusammenfassung:	A method and a system for the detection and passivation of an electric arc on at least one connecting element of an electrical device. The system comprises an acoustic acquisition channel configured for the acquisition of acoustic signals emitted by the connecting element, an electric acquisition channel configured for the acquisition of electric signals which are representative of the electric current intensities supplying the connecting element, and a correlator coupled to the acoustic and electric acquisition channels, configured for the evaluation of a correlation between the acoustic and electric signals and for the tripping of an appropriate cut-off signal for the interruption of an electric circuit relative to the connecting element, where the correlation is representative of the initiation of an electric arc.
