description: This work is devoted to identifying the influence of the level of voltage asymmetry on electrical energy losses in electrical networks of 0,4 kV. Tasks that were solved in the course of the study: 1. Consideration of the structure of electrical energy losses in networks and the reasons for their occurrence; 2. Study of the concept of "voltage asymmetry" and the issue of ensuring the quality of electricity at enterprises; 3. Researching the issue of choosing optimal configurations and assessing voltage modes at enterprises; 4. Carrying out a theoretical and practical calculation of electricity losses and identifying the influence of asymmetry on electricity losses. The practical part of the calculations was carried out on the basis of CJSC "Khimeks", where a single-line power supply diagram and data for calculations were taken. According to the results of calculations, it was revealed that asymmetry has a significant impact on the loss of electrical energy in the 0.4 kV network. Measures were proposed to reduce the level of voltage unbalance.
