Beschreibung
Zusammenfassung:	FIELD: electricity. ^ SUBSTANCE: invention relates to electrical engineering. For this purpose, the method provides for loads balancing in 0.4-6(10) kV lines phases and 6(10) kV reducing transformers by switches connecting loads to 0.4 kV power transmission lines phases with receiving devices. Control signals from microcontroller transmitter-receiver are supplied to the above-mentioned receiving devices. The current sensors used in microcontroller are installed between power transmission line and load. The loads are switched over based on a condition that current unbalance factor is minimized in 0.4 kV power transmission line. ^ EFFECT: reduction of current unbalance factor and power losses and extension of transformer and cable lines lifetime. ^ 1 dwg
