description: This work is devoted to the study of switching overvoltages. The first three parts are devoted to theoretical information not only about the switches themselves, which are most popular in 6(10) kV networks, but also about transients, and about the threat of overvoltage for electrical equipment. The process of changing the volt-age on the circuit breakers and on the load when switching vacuum circuit breakers that are in parallel was considered. A shutdown model was created in the Matlab Simulink pro-gram, and data obtained from the testing stand was presented. The paper also presents the results of experiments that were carried out in the Talc software. All charts are analyzed. Based on the analysis of the data obtained, it was found that switching switches with a very small time difference between disconnections, although small, is likely and carries a great danger to the equipment. As an additional measure of protection, it was proposed to introduce additional surge arresters with a large class of energy consumption.
