Abstract: A process for identifying the usage of electrical equipment connected to a power supply grid has an asynchronous motor coupled to a charge including identifying the usage of the electrical equipment by using an electrical signature of this equipment. The electrical signature is determined in a previous step and consists of a limited and predetermined set of characteristic frequencies and their harmonics obtained from the only information featuring on the identification plate of the asynchronous motor, and from visual inspection of the charge and its method for coupling to the asynchronous motor.
