[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT Analysis of performance and reliability of electrical equipment of high-voltage electrical systems (hereinafter - HVES) confirms the need to improve evaluation methods and mathematical modeling of transients in power lines (hereinafter - PL), at substations, and in grounding and protective devices. One of the main problems, however, remains improvement of safety and quality of HVES functioning in accordance with their EMC in modes of overvoltage effects, including determination of evaluation criteria, scientific substantiation of deep forced restrictions of external and internal overvoltage of electrical equipment, optimization of PL protection and substations of the system from different levels of voltage, electromagnetic interference that could cause serious accidents. Keywords: railway infrastructure, electrical power supply, electromagnetic compatibility, high-voltage electrical systems, lightning overvoltage, neutral of transformers. REFERENCES 1.Bader, M.
