Szukana fraza: [Abstrakt = "The article presents simulation results related to the phenomenon “spectrum leak” in the process of assessing the quality of electricity. At the beginning, the article discusses issues related to the problem of the need to analyze the quality of electric energy and the phenomenon of \"spectrum leakage\" associated with this analysis. Subsequently, the analyzed signals were presented along with their functional description. For the discussed runs, FFT spectral analysis was performed using the MATLAB program. During the simulation, the frequency of the tested signal was changed in the range of acceptable voltage deviations of the network defined by the appropriate standard. When changing the frequency, the error of measuring the content of higher harmonics was tested using window function. The article ends with the collection of conclusions from the analysis and the summary."]
