description: In the course of the work, electric power systems of 10/6.3 kV, 6.3/0.4 kV of various power were investigated. At the initial stage, typical schemes for the study were selected. After that, a choice was made of the electrical equipment of the systems under consideration, namely transformers, asynchronous electric motors, cable lines, busbars, switches, automatic switches. Next, two power systems of 10/6.3 kV of different power were considered using different sections of the outgoing cable line, the three-phase short-circuit current was calculated taking into account the motor load and without to determine the manifestation of the shunting effect of asynchronous electric motors. In addition, three 6.3 / 0.4 kV power systems of different power were considered, but with the same cross section of the outgoing cable line. At the same time, three-phase and single-phase short circuits were calculated. According to the results of calculations, when considering each electric power system, the values ââof the remoteness of the short circuit point from the busbar were obtained when the shunting effect of asynchronous electric motors was manifested.
