The paper presents the results of a simulation research showing the problem of "spectrum leakage" in harmonic measurements. At the beginning, the paper discusses issues related to the need to analyze the power quality and the phenomenon of "spectrum leakage". Subsequently, for the test signals, measurement of harmonics in accordance with the applicable standard, was performed. During the simulation research, the frequency of the tested signal was changed in the range of acceptable deviations of the frequency of the voltage in the power grid determined by the appropriate standard. The harmonic measurement error was determined, with the known spectrum of test signals. Metrological interpretation of the obtained results, and formulations of conclusions were presented in the paper.
