Abstract

Electric energy metering system consists of watt-hour meter, voltage transformer and current transformer. Hence, the error of electric energy metering system should be analyzed from the three parts. Aiming at the measurement accuracy of the power metering system under harmonics, the equivalent circuits of electronic watt-hour meter, capacitive voltage transformer and magnetic current transformer under harmonic conditions are built, and the harmonic measurement/metering error and the influencing factors are analyzed. The model of electric energy metering system is set up to analyze its error under harmonic conditions. This article provides a theoretical basis for the quantitative analysis of measurement error of the energy metering system under harmonics.
