Abstract: The paper presents the study of high harmonics influence on power metering by static meters for active and reactive energy. The review and analysis of manufacturer’s documents and standards in the field of electricity meters testing was conducted and mathematical models for calculating active and reactive energy were identified. Various electronic meters were tested at the experimental stand. As a result, the errors of active and reactive energy metering in the presence of high harmonics were determined. It is shown that the implemented in static meters equations for the active and reactive energy calculation can lead to unfair payments for electrical energy in the presence of high harmonics.
