The total energy waste of standby power estimated by Organization for Economic Cooperation and Development(OECD) is 124 TWh. In order to know the energy waste by standby adapter, status identification of plugged-in adapters is necessary. Studies indicate that distinguishing an status of adapters from others is to recognize its load pattern; the load pattern identification requires history data. This paper ﬁnds that the pattern of current varies with inrush current of diﬀerent adapter status are distinct and it is possible to use inrush current for adapter status identification. With a full deployment of Advanced Metering Infrastructure (AMI), every electric customer is equipped with a smart meter. This meter is capable of making a high frequency measurement, having a data storage and communicating with utilities. Bennett, C. and Highﬁll, D. indicate that a smart meter also acts as a home console for monitoring energy consumption. This paper proposes us an algorithm that utilizes the consideration platform in embedded within smart meters to identify the specific adapter in a home circuit.
