Discussion on “the practicability of large generators wound for 22,000 volts,” at New York, March 22, 1907

I stated that hydraulic turbines for large capacity, of 7500 kw. or above in individual units, are not likely to be of great importance at the present. The extensions at Niagara Falls may contain such large individual units; I hardly think that for the Victoria Falls of the Zambesi, units of 7500 kw. will be installed. Our chairman, Mr. Mershon, will probably bear me out when I say that the units for Victoria Falls will be about five thousand kilowatts. In all these cases the line potential will be high, and, therefore, the generators will not have t o be wound for very high potentials. I believe, therefore, that my statement, that water-wheels need not seriously be considered as prime movers for large generators wound for high potential, is correct.
