The turbines are constructed for a fall of from 52 to 55 a flow of from 960 to 910 litres of water per second withan efficiency of 75 per cent when developing 500 h. p. at 400 r. p. m. The turbines were built in the shops of Piccard, Pictet & Co.,Geneva, and are of the centrifugal type with horizontal staflf. Theadjusting may be made by hand or by means of a servo-motoractuated by the shaft of the turbine. A centrifugal governor servesas relay so that the number of revolutions always remains the same. The generators, each of 425 kw. capacity, are connected to theirrespective turbines by flexible insulated couplings. At 400 r. p. machines deliver current at 8,000 volts, the periodicity being53 1-3.
