Main Lines Hybrid Device for Symmetrizing Phase Currents for 0.4 kV

The relevance of this topic lies in the need to increase the reliability of electrical systems and to enable more efficient use of existing resources for energy production. The application of a hybrid phase balancing device for 0.4 kV busbars allows for significant reduction of risks of emergency situations and improves the quality of internal energy distribution within the system. An analysis of electrical load profiles and 0.4 kV busbar lines has been conducted, technical data of the hybrid phase balancing device has been studied. Voltage losses in the 0.4 kV lines have been determined, maximum current loads and short-circuit currents have been calculated. The selection of the installation location for the balancing device has also been discussed. The type of hybrid phase balancing device has been chosen. Suggestions for improving energy efficiency have been proposed, and energy savings have been calculated.
