description: The focus of this research is to investigate and analyze overvoltages occurring at transformer substations and the development of a method of protection against them using nonlinear surge limiters (OPN). Tasks that were considered during the study: 1. Study of the device and the principle of operation of the OPN, consideration of its technical characteristics, types and design. 2. The requirements for the design of nonlinear surge arresters are given 3. The analysis of the operating conditions of the transformer substation under pulsed voltage surges is carried out 4. The method of selecting the main parameters of the OPN for a 6-35 kV network is presented 5. In the Matlab Simulink environment, a 10 kV transformer substation model was developed 6. The calculation of the effective value of the intermittent component of the current of three-phase and single-phase metal short circuit is carried out According to all the results of the calculations of the parameters necessary for the selection of surge limiters, as well as when comparing the voltage values on consumers, busbar and switch, the devices of the OPN company Tavrida-Electric LLP were selected.
