FIELD: electricity.
SUBSTANCE: invention can be used in electrical engineering. The system contains first, second and third windings, magnetically connected to the transformer core of a power supply. The system also contains a first low-voltage contactor and a second low-voltage contactor. The system further contains a first low-voltage impedance element, connected between the first low-voltage contactor and the first winding, a second low-voltage impedance element, connected between the second low-voltage contactor and the first winding, a third impedance element, connected between the first low-voltage contactor and the second winding, and a fourth low-voltage impedance element, connected between the second low-voltage contactor and the second winding.
EFFECT: more reliable protection from inrush current.
