description: The purpose of this work was to create a working model of a nonlinear overvoltage limiter of suspended version for voltage class 330 kV in the program âComsol Multiphisicsâ to study the electrothermal processes occurring in the device when it is exposed to lightning discharge. Thus, several objectives can be emphasized: 1. studying the scientific literature to establish the theoretical basis necessary to build a model of a nonlinear voltage limiter and to conduct performance tests. 2. Development of a mathematical model of polymer insulated surge arresters of suspended design for the voltage class 330 kV. 3. Modeling of tests in accordance with GOST. According to the results of modeling of the arrester tests with three types of test pulses it became clear that the investigated protective device passed the tests without exceeding the value of the highest permissible residual voltage and limits overvoltages without reaching temperatures that can lead to its failure. In addition, a model was created to calculate an electrostatic problem: finding the distribution of electric field strength around the arrester in order to determine the effective location of the equalizing shields.
