Abstract
The influence of conducted electromagnetic disturbances on the energy measurement error of electricity meters remains insufficiently explored in electromagnetic compatibility (EMC) studies, particularly in the frequency range above the classical harmonic domain. The aim of this study was to investigate the susceptibility of electricity meters with different input configurations to conducted disturbances in the frequency range 1-150 kHz, including the 2-150 kHz band covered by IEC 61000-4-19. The novelty of this work lies in the comparative analysis of meters employing a shunt resistor, current transformer, Rogowski coil, Hall-effect sensor, and a digital system based on a Merging Unit and Sampled Values. The tests were performed as a preliminary screening stage of the study, using a test procedure based on IEC 61000-4-19, in which the energy measurement error was determined from the difference between the energy measured by the meter under test and that measured by a reference meter while disturbances were injected into the current circuit. The results showed that, for most of the tested electronic meters, the influence of the disturbances at the applied 1 A level was limited. For the tested Class B meters, the observed maximum error deviations remained below 1%, while the largest deviation under continuous-wave disturbance was observed for the Merging Unit + SV system. The highest immunity to amplitude-modulated disturbances was found for the shunt-based meter and the Rogowski coil-based meter. In none of the investigated cases were large error deviations on the order of several percent or several tens of percent observed. The obtained results indicate that, under the applied test conditions, conducted disturbances in the investigated frequency range did not cause significant deterioration of the metrological performance of most of the analyzed electronic meters. However, the results should be interpreted as a comparative assessment under modified IEC-based test conditions, rather than as a full compliance evaluation at the normative disturbance levels for directly connected meters.
