Abstract in different language:	In the introduction of the presented work, the physical nature of the collapse of electrical energy transmission systems due to the influence of a magnetic storm is recalled. A mechanism is described by which, due to the non-linearity of the magnetic circuit of the system's power transformers, quasi-direct currents are induced into the high-voltage part of the system, which cause thermal overload of these transformers. The article then suggests one of the possible ways to prevent these accidents. On the single-phase and then on the three-phase model, it is shown how these currents can be compensated. Using laboratory models, the compensation process was simulated and verified by measurements.
