<p>A method is disclosed for identifying the various equipment (loads) on an electric circuit by non-invasive measurements, i.e. not requiring installation of equipment other than a suitable electric meter, for determining the portion of total consumption attributable to each equipment, and for classifying consumption in tabular form for later use. The method involves making appropriate measurements on the electrical supply current for the circuit to determine the variations in impedence of the circuit loads with time, identifying said loads by determining the portion due to an amplitude effect and the portion due to a phase variation, classifying these applied loads in a table, and calculating the consumed power for each type of previously identified and classified load.</p> |
