Westinghouse synchronous alternator

Download

Workers pose in 1891 with a 100-hp Westinghouse synchronous alternator at the Ames power plant located near Ophir, Colorado. At the time, it was the largest alternator Westinghouse made. It was used as a generator, connected by a belt drive to a 6-foot Pelton water wheel driven by water from the San Miguel River. It produced a 3000-volt, 133-Hertz, single-phase alternating current to drive a similar alternator connected by copper power lines 2.6 miles long that acted as a motor to drive a stamp mill at the Gold King Mine. It replaced an existing steam mill that was difficult to run because of a lack of timber to use as fuel. (Source: Wikimedia Commons. Public domain.)
