Abstract
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.
