A method of detecting tripping of an interrupting apparatus in an electrical cabinet , said electrical cabinet comprising at least one electrical current interrupting apparatus and at least one electrical current switching apparatus , the method comprising a learning phase suitable for generating decision-making categories associated with an acoustic signature of the tripping of said at least one switching device , and a phase of detecting the tripping of the switching device comprising steps consisting of: - acquiring a device noise signal generated by at least one of said electrical current switching devices or at least one electrical current switching device , and - comparing said device noise signal with said decision making categories to detect whether the device noise signal corresponds to triggering of the mute device , the detection method being characterised in that the learning phase comprises steps of: - injecting a predetermined switching current into the switching device and recording the switching noise signal generated, - sending the mute noise signal to an automatic learning system capable of recognising the acoustic signature of the mute device and outputting discrete mute values, - grouping the discrete cut-off values to create the decision-making categories , - injecting a predetermined current into the switching device and recording the switching noise signal generated, - sending the switching noise signal to the automatic learning system and obtaining discrete switching values as an output, - discriminating between discrete switching values and discrete cut-off values by modifying the decision making categories so as to exclude discrete switching values which fall into those decision making categories . - acquiring a device noise signal generated by at least one of said electrical current switching devices or at least one electrical current switching device , and - comparing said device noise signal with said decision making categories to detect whether the device noise signal corresponds to triggering of the mute device , the detection method being characterised in that the learning phase comprises steps of: - injecting a predetermined switching current into the switching device and recording the switching noise signal generated, - sending the mute noise signal to an automatic learning system capable of recognising the acoustic signature of the mute device and outputting discrete mute values, - grouping the discrete cut-off values to create the decision-making categories , - injecting a predetermined current into the switching device and recording the switching noise signal generated, - sending the switching noise signal to the automatic learning system and obtaining discrete switching values as an output, - discriminating between discrete switching values and discrete cut-off values by modifying the decision making categories so as to exclude discrete switching values which fall into those decision making categories . - injecting a predetermined switching current into the switching device and recording the switching noise signal generated, - sending the mute noise signal to an automatic learning system capable of recognising the acoustic signature of the mute device and outputting discrete mute values, - grouping the discrete cut-off values to create the decision-making categories , - injecting a predetermined current into the switching device and recording the switching noise signal generated, - sending the switching noise signal to the automatic learning system and obtaining discrete switching values as an output, - discriminating between discrete switching values and discrete cut-off values by modifying the decision making categories so as to exclude discrete switching values which fall into those decision making categories . <EOS>
