A method for analysing the consumption of electricity of a site equipped with a plurality of items of electrical equipment of different kinds, comprising at least one sensor for the periodic measurement of the current and/or voltage on at least one of the electrical phases upstream of the network supplying the site, as well as a computer for carrying out processing said method comprising: sampling at least the current signal; applying a Fourier transform to each fundamental period of the current signal; smoothing of said transformed signal; forming a database of signatures; recording, during a long period, candidate signatures liable to be associated with a variation in consumption of one of said items of equipment; and next using said database of reference signatures for qualifying the events occurring on said network. |
