Power for the Paris-Versailles line is being supplied from astation at Moulineaux. along the line of route, at 5500 volts. 25cycles, which is converted by rotaries into direct current at 550volts. There are three main sub-stations, each of which containfour Thomson-Houston rotary converters of 300 kw each. Thepressure is regulated on the alternating current side by a regu-lating transformer with a movable armature, permitting a varia-tion of 15 per cent. The rotaries are started by direct current,supplied by a 40-kw generator, driven by an induction motor. A view of one of the sub-stations of the company, of which thereare three, one at the Champs de Mars, one at Meudon. and oneat Viroflay, is shown in Fig. 9.
