transmission, consisting of generators, transformers and high-voltage transmission lines. His system allowed the distribution of electrical power over wide areas. He used the system to light offices and stores along the main street of Great Barrington - the location of his West Avenue family home. Stanley's transformer design became a prototype for future transformers, and his AC distribution system formed the basis of modern electrical power distribution. His work in the electrification of Great Barrington's Main Street was named an IEEE Milestone. Agreeing that the AC system had arrived, Westinghouse further tested the system in summer 1886 in Pittsburgh; it transmitted over a distance of 3 miles, and used an alternator designed by Stanley to replace the Siemens model, which regulated voltage poorly. Satisfied with the pilot system, Westinghouse began commercial production and shipped his company's first commercial to
