Abstract
The present disclosure relates to a method for detecting an electric arc in an electrical system (), comprising the following steps: a) acquiring a signal () coming from at least one sensor () detecting acoustic waves in the system (); b) calculating, using an electronic processing device (), a first value representative of the error between the signal and a first projection of the signal in a first representation space defined by a first dictionary matrix; b) calculating, using the electronic processing device (), a second value representative of the error between the signal and a second projection of the signal in a second representation space defined by a second dictionary matrix; and d) determining, from the first and second values, whether an electric arc has been produced in the system.
