This article aims to study the influence of electromagnetic interference on the testing of electric energy meters and corresponding protective measures. By combining experimental and theoretical analysis, this study focuses on the impact of electromagnetic interference on the accuracy of electric energy meter testing, including measurement errors, data instability, and equipment damage. Based on these factors, this article proposes protective measures against electromagnetic interference, including the application of physical shielding technology, reasonable design of filters, and strict attention to the testing of electric energy meters. The results indicate that electromagnetic interference can lead to increased errors in electric energy meter testing, which can cause malfunctions and even incorrect operations. To minimize the impact of electromagnetic interference, this article proposes a series of effective protective measures, including reasonable wiring, installation of filters, and use of shielded cables. These measures have achieved good results in practical applications and significantly improved the accuracy and stability of electric energy meter testing.
