Abstract

This paper describes a signature construction for identifying loads based upon harmonic content of the current measured at a metering socket. Data gathered from ten loads at a commercial site served to experimentally validate the signature construction. The repeatability of current harmonics was investigated during transients and steady-states of several single, split-phase, and three-phase loads monitored in isolation
