PROCEDE ET SYSTEME DE PROTECTION CONTRE LES ARCS ELECTRIQUES METTANT EN ŒUVRE UNE MODULATION SPECIFIQUE A UN MODULE DE L'ONDE ACOUSTIQUE ACCOMPAGNANT UN ARC ELECTRIQUE

摘要

The invention relates to an electrical system comprising a plurality of modules that can be powered independently withy current, characterised in that it further comprises: a module configured to apply to each of the modules a current which is modulated by a signal specific to the module, an acoustic sensor enabling the measurement of an acoustic signal that accompanies an electrical arc generated by a defective module, a treatment unit configured to identify a signature of one of the specific signals in the acoustic signal measured by the acoustic sensor in order to identify the defective module. The invention also relates to a method for locating faults in such an electrical system.
