Profile of George Westinghouse
音量
Hi, I'm Christina Hartman for About.com and today we're profiling the American engineer George Westinghouse.George Westinghouse was born in October 1846 in Central Bridge, New York. As a teenager, he served with the New York National Guard and the Union Army and Navy during the Civil War. After the war, he took an interest in engineering and by the age of 21 had already invented a rotary steam engine, a farm engine and several improvements for railroads.In 1869, he developed the air brake for railroad cars. Formerly, train engineers had to go to each rail car to individually apply the brakes. After witnessing a train wreck because of the old braking system, he developed a system using compressed air that ran the length of the train and could be simultaneously applied to each car. He patented the air brake in 1872 and also developed improvements for railway signals.Westinghouse also took a great interest in the new concept of electricity. At the time, Thomas Edison and Nikola Tesla were arguing about whether Edison's direct current or Tesla's alternating current would become the standard distribution system for electricity. Westinghouse considered both systems and came to the conclusion that Edison's direct current was too inefficient to be used on a large-scale as it lost a large amount of power.After seeing a demonstration of a transformer for alternating current in London, Westinghouse got to work on refining the design of transformers and building a power network based on AC. In 1886, he installed the first alternating current system in Great Barrington, Massachusetts. He continued to make improvements to the system which had been installed in a number of other areas and even hired Nikola Tesla as a consultant. Their designs would go on to form the basis for the entire distribution of power in the United States during the modern era.
In 1911, the American Institute of Electrical Engineers awarded Westinghouse the Edison Award for his work with alternating current. Westinghouse died in March of 1914.
