FIELD: electrical engineering. SUBSTANCE: current limiters are inserted in control valve circuits of each phase. Circuits obtained are connected in delta; controlled resistors of each phase are cut in between tops of delta connections and common point of controlled valve and current limiter. EFFECT: facilitated turn-out of controlled valves and reduced power requirement. 7 cl, 1 dwg
