Electromagnetic Compatibility of Electric Energy Meters in the Presence of Directional Contactless Electromagnetic Interference Illia Diahovchenko and Bystrík Dolník
Introduction Electric energy meters (EEMs) are used in private households and industry to measure the electricity consumed. Consumers with high electric energy demand require accurate data to make energy management decisions, while utilities collect big data arrays to improve their services. Therefore, there is a pronounced tendency towards the use of electronic static and digital EEMs for registration of electric energy flows and for billing purposes [1]. Contemporary smart meters are built on integrated microcircuits, which allow to perform more value-added features, along with compactness of size. The multidimensionality of the requirements for the computational capabilities of the microprocessors stimulates the complication of the electric energy metering devices’ architecture. State-of-the-art meters are equipped with options of remote sensing, power quality monitoring, recording of tampering events with time stamping, multi-tariff billing, Internet connectivity, peak demand, etc. [2]. The above-mentioned advances in technology have stimulated the topicality of the electromagnetic interference (EMI) issues. The circuitry/subassemblies of equipment in use can emit electromagnetic energy, which can corrupt the performance and accuracy of the sensitive elements of an EEM. Malfunction of EEMs when used in combination with photovoltaic (PV) inverters has been reported in [3–5]. The authors of the work [3] reported a gap in standardization of emissions and electromagnetic immunity in the 2–150 kHz range. Moreover, manipulation with strong magnetic

fields can be employed for tampering purposes [6]. Events such as switching of inductive loads lightning, electrostatic discharges, and the presence of telecom, radio and video broadcast signals cause some types of EMI. It is essential to produce EEMs that are electromagnetically compatible [2]. Consequently, the regulations associated with the high-frequency electromagnetic interference suppression are steadily tightened [7]. The purpose of this work is to verify the EMC performance of contemporary power meters and to emphasize the urgency of the EMI issues that already seemed resolved in the twenty-first century.
Applicable Standards The common standards for EMC of power meters were established by the American Standards Institute (ANSI) or International Electrotechnical Comm
