Measurements-based Method for Impedance Characterization of Residential Loads

IEEE Instrumentation and Measurement Technology Conference - IMTC 2004, Como, Italy, May 2004.

Abstract: The load impedance characterization problem in the residential environment is addressed in this work. The transfer function of any point-to-point link in the indoor power line environment depends on the communications characteristics of the medium and the presence of residential loads, in the form of electrical appliances. Measuring the transfer function changes in an experimental set-up that are caused by an unknown residential load can be exploited to determine the value of its impedance. In this paper, we propose two new methods for such determination and analyze their accuracy and performance limitations.
