The topic of this thesis is Parameter selection and application of surge arresters in the distribution network. To begin the work, a description of the basic characteristics of metal-oxide surge arresters intended for installation in the distribution network is given. Their advantages compared to other materials used to make surge arresters are defined. Then, possible voltage stresses that may arise due to the appearance of overvoltage in the network were mentioned. Temporary, switching and atmospheric overvoltages were taken as authoritative overvoltages. For each of the listed overvoltages, different situations of their occurrence were taken. In addition to the aforementioned overvoltage situations, emphasis was also placed on the possible treatment of network grounding, as well as the consequences of the grounding method on the very choice of surge arrester parameters. At the very end, the example of TS 110/20 kV is taken, where the surge arrester is selected for real parameters. The choice of surge arrester is based on the analysis of voltage stresses, processed in the paper.
