The paper provides reviews of scientific works dedicated to the probability of resonant phenomena occurring in electrical grids, which are caused by non-sinusoidal operating modes. The authors studied various methods for calculating and predicting resonance and drew necessary conclusions. The analysis of these articles indicates that the phenomenon of resonance poses a danger to electrical equipment, as partial or complete technical damage to the equipment can occur during its onset. To mitigate the influence of resonant phenomena on electrical equipment, it is necessary to use controlled shunts, static capacitor banks, controlled shunt reactors, and other means. At the end of the article, a table summarizes the methods used for the resonance phenomenon, along with the conclusions and recommendations of various authors.

Keywords: resonant phenomenon, nonlinear loads, electric networks, higher harmonics.
