The threetransformers, which are delta connected on both the primaryand secondary sides, are each of 110 kilowatts capacity andstep down the voltage from 26,400 to 370 volts. The threetransformers feed into an alternating-current rotary panel ofthe switchboard which is thoroughly equipped to control therotary. The three-phase. 25-cycle, rotary converters are of 300kilowatts capacity, designed for 370 volts on the alternat-ing-current end. The direct-current voltage is 600, the cur-.
