Nonintrusive load meters (NILMs) with a load identification ability have been developed in several institutes and companies. All load identification algorithms (LIAs) have a common characteristic: load identification is based on the current waveform.

This paper describes mathematical modeling of cage-type ac current shunts. A calculable model was developed using lumped circuit elements. The transimpedance, ac–dc difference, and the phase angle error of a shunt can be derived from the model. An
