A 1,000-kw. Wind-driven Electric Generator Top of page go up A PLANT which is tell to represent the first honest attempt to make the times of electricity by move up power on much(prenominal) a scale that its practical and sparing possibilities may be judged, is exposit in Engineering of July 31. The beat up consists of a two-bladed wind-turbine and a 1,000-kw. alternator mounted on a pintle girder on the top of a lattice steel jerk cx ft. high, and it has been erected on the raising of a 2,000-ft. mountain known as Grandpas Knob, near Rutland, in the State of Vermont. Though in a sense the plant is experimental, the current generated will be utilize upd by the central Vermont Public Service Corporation. It has been estimated that it will be possible to use the power of the wind for 4,000 hours a year. The blades of the turbine be each 65 ft. long and 11 ft. wide and number 15,300 1b. The circle described by the ends of the blades is 175 ft. in diam and at 28-7 r. p. m.

the fish speed is 15-785 ft. per minute. The alternator is driven through cogwheel and generates three-phase current, 60 cycles and 2,300 volts. The graphic designer of the wind turbine, Mr. P. C. Putnam, has had the assistance of others, and pattern tests of his turbine were made in the wind tunnel of Stanford University. There ar many interesting features in the plant, and so that an exhaustive study of wind variations can be made an anemometer tower 180 ft. high has been erected adjoining by and fitted with three types of anemometers.If you indispensability to get a proficient essay, order it on our website: BestEssayCheap.! com
