A method and apparatus for characterizing a circuit coupled to an AC line. The apparatus comprises a consumption measurement unit (CMU), adapted for coupling, independent of voltage and current polarity, to the AC line and the circuit. The CMU comprises a discovery module adapted for (i) generating a circuit current signature based on current samples representative of current on a phase of the circuit, (ii) generating at least one AC line current signature based on AC line current samples representative of current on each phase of the AC line, and (iii) determining, based on the circuit current signature, the at least one AC line current signature, and at least one of a source profile or a load profile, at least one of a type or a voltage characteristic for the circuit.

La présente invention concerne un procédé et un appareil pour caractériser un circuit couplé à une ligne CA. L'appareil comprend une unité de mesure de consommation (CMU), conçue pour se coupler, indépendamment de la polarité de tension et de courant, à la ligne CA et au circuit. La CMU comprend un module de découverte conçu (i) pour générer une signature de courant de circuit sur la base d'échantillons de courant représentatifs du courant sur une phase du circuit, (ii) pour générer au moins une signature de courant de ligne CA sur la base des échantillons de courant de ligne CA représentatifs du courant sur chaque phase de la ligne CA, et (iii) pour déterminer, sur la base de la signature de courant de circuit, la ou les signatures de courant de ligne CA, et au moins un profil de source ou un profil de charge, au moins un type ou une caractéristique de tension pour le circuit.
