FIELD: electric power supply. SUBSTANCE: system has supply mains, power transmission line, and two transformers. Primary windings of transformers are interconnected in parallel and connected to two switchgear cubicles. Electric motors and abruptly varying load are connected to them so that both motors and abruptly varying load are closed to secondary windings connected in series opposition, that is, to main secondary winding of one transformer and to compensating winding of other transformer. EFFECT: facilitated voltage regulation across collecting buses and starting currents limiting when throwing electric motors on line. 6 dwg
