description: The issues covered in the present work are as follows: 1. creation of a 220 kV power line model. 2. creation of a surge arrester model. 3. equipping the power line support models with the arrester models. The first case we deal with one device, placed at the top phase. Second one implies the installation of surge arresters at both top and lower phase. 4. calculation the amount of energy that flows through protective electrical equipment under external impacts with different pulse duration, considering the place of direct lighting strike (the middle part of the span, the power line support). 5. Calculation of the probability of lightning occurrence with preset parameters, as well as its dependence on the total energy flowing through surge arresters. The analysis of the results was carried out by mathematical modeling using EMTP-RV program, while calculations and visualization of data in the form of graphs were obtained with the help of Mathcad and Excel software packages.
