description: In this paper, the issue of lightning protection of the 500 kV "Zhitikara â Ulke" overhead line without a lightning protection cable when using EGLA is considered. The main lightning parameters are analyzed, as well as the consequences of a lightning strike for sections of a line with a conducting current, and various methods of preventing lightning overvoltages are considered. Using the EMTP software package, a simulation of a high-voltage line was carried out to calculate lightning overvoltages. As a result, the effectiveness of lightning protection for a 500 kV high-voltage line was evaluated in the presence and absence of lightning protection devices. The introduction to the work contains a brief description of the problem of lightning protection of overhead lines and justification of the relevance of the study. The absence of a lightning protection cable on the 500 kV Zhetikara-Ulke overhead line caused the need to develop alternative methods of protection, which is the main motive for conducting this study. The first part of the work is devoted to a review of the literature and analysis of existing methods of lightning protection of overhead lines. The second part of the work describes the study of lightning protection of 500 kV overhead line "Zhetikara-Ulke" with the use of EGLA. Measurements and comparative analysis of the results obtained with the use and absence of EGLA were carried out. The third part of the work is devoted to the analysis of the results and conclusions. The data confirming the effectiveness of lightning protection of 500 kV overhead line "Zhetikara-Ulke" using EGLA are presented.
