FIELD: electrified ac railways: power supply. SUBSTANCE: secondary winding of booster transformer is connected at break of phase C, and primary winding is connected to traction winding of one of phases of traction transformer. This provides complex control of voltage level in both supply arms, reduction of equalizing current in intersubstation zone and limiting of maximum instantaneous short-circuit current in emergency. EFFECT: enhanced efficiency of reduction of equalizing current and limitation of maximum instantaneous short-circuit currents on feeders of contacts system. 3 dwg
