Each dynamo gives 275 amperes at 600 volts, and is10 feet in diameter, the armatures measuring 8 feet 6inches. The dynamos weigh 19 tons each. The shafts are vertical, and, as stated, direct coupled to the turbines,the field magnets being supported on special far as we know, these machines enjoy the title tothe distinction of being the largest direct currentmachines built of this type, but on account of the slowspeed are not nearly as effective as they might be with a.

The power is taken from the Arve river, with600-horse-power available as a minimum, with a dropfrom the head to the tail race of only 10 feet. Todevelop the power three turbines are used, one for weekdays supply, one for Sundays and holidays, and one as a m.
