Large Water Wheel Alternators The Cliff Electrical Distributing Company of Niagara Falls,which takes power off the turbines of the Niagara HydraulicPower Manufacturing Comijany, have just placed an order withAlHs-Chalmers Conipanv for another fwOO volt. t • • •. The .Sixlb (),.|()(» , (jenerator being the ClilT Company. three phase, S-l cycle alternator (see figure). Tliis makes thesixth of large machines to be installed in the new powerhones of this company. These alternators have hren of particular int(;rest to theengineering profession because of the unuHual and geculiMfeatures of their design and made necessary by the conditions of operatiou. On account of the possibility,which is often present in hydraulic turbine installations, of theturbine running at excessive speed, it was necessary to constructthe alternators so that they would be safe under runaway con-ditions. The nurmal speed of these machines is 300 , butthey are designed with an over speed safety factor of 7-j percent., which enables them to rim safely at • , or aboutfive times as great as that of machines of the same capacitywhen driven by steam engines.
