Analysis of Transient State Signatures in Electrical Household Appliances

Abstract

The paper presents the analysis of the transients occurring in the current patterns during switching on the selected electrical appllances operating in the typical apartment. Knwoledge about behavior of such devices is important for their non-intrusive identification and subsequent determination of the energy consumption. The problem with the transient measurements and processing is presented, focusing on its exploitation for the generic applicance identification framework. Experiments presenting the phenomenon during various device configurations are presented. The generic methodology to accurately process transients and use them to increase the accuracy of the appliance identification is proposed.
