Zusammenfassung:	A method of inference of appliance usage from a point measurement on a supply line, said supply line being common to multiple appliances and/or components of appliances comprises the steps of: obtaining data from said measurement point; sampling power and reactive power at intervals substantially throughout periods of operation of said appliances or components of appliances corresponding to appliances or components of appliances being in ON and/or OFF modes of use; identifying characteristics of events by assessing power and reactive power change during an event; and by assessing one or more additional characteristics derivable from said power and reactive power to characterise an appliance; grouping events and/or cycles of events into clusters of similar characteristics; and inferring appliance usage based on said grouping. L'invention concerne un procédé de détermination d'utilisation d'appareil à partir d'une mesure ponctuelle sur une ligne d'alimentation, ladite ligne d'alimentation étant commune à des appareils et/ou des composants d'appareils multiples. Le procédé comprend les étapes suivantes : obtention de données depuis ledit point de mesure; échantillonnage de la puissance et de la puissance réactive à des intervalles pratiquement tout au long des périodes de fonctionnement desdits appareils ou desdits composants d'appareils correspondant aux appareils ou aux composants d'appareils étant dans des modes d'utilisation MARCHE et/ou ARRET; identification de caractéristiques des événements par l'évaluation du changement de puissance et de puissance réactive pendant un événement; et par l'évaluation d'une ou plusieurs caractéristiques additionnelles déductibles desdites puissance et puissance réactive pour caractériser un appareil; groupage d'événements et/ou de cycles d'événements en groupes de caractéristiques similaires; et détermination de l'utilisation d'un appareil en fonction dudit groupage.
