FIELD: electricity. ^ SUBSTANCE: invention is related to the field of transmission and distribution of electric power and may be used for limitation of short circuit current value in mains and load, and also in systems of AC power supply sources redundancy. According to the method, in transmitting substation three-phase AC voltage is transformed into two three-phase voltage systems with unidirectional opposite currents, and power is transmitted through six-wire distribution network, at the end of which reverse transformation of voltage is carried out back into three-phase AC voltage by summation of magnet flows in magnetic conductor of three-phase transformer with split primary windings. ^ EFFECT: reduction of short circuit current value, reduction of loss in mains with reduction of requirements to breakers on their disconnecting capability, reduction of total section of supply current conductors, reduction of material expenses. ^ 2 cl, 3 dwg |
