The accuracy of energy metering devices has a significant impact on maintaining fair trading in the electricity market and ensuring the measurement of user electricity consumption, but their operation is susceptible to near-field electromagnetic interference. The aim of this study is to investigate the specific impact of near-field electromagnetic interference on the performance of electric energy metering devices. Firstly, the basic concept of near-field electromagnetic interference and its impact on measuring devices were described. Secondly, the induction voltage and attenuation characteristics of near-field electromagnetic interference on magnetic field antennas at different distances were simulated. Finally, the performance of the measuring device under interference environment was tested, and the experimental data was analyzed to obtain the quantitative relationship and variation law between the near-field electromagnetic interference intensity, frequency, distance and the measurement error of the measuring device.
