Westinghouse company´s Fortieth anniversary

Just 40 years ago, George Westinghouse started his career in the field of electricity. On May 20, 1884 he signed a contract with William Stanley, whose great gift to the industry while connected with Westinghouse was the development of the transformer, which has made possible the long distance transmission of alternating current at relatively high voltages, reducing it to low, usable voltages at the necessary points. Beforethis time direct current only was used.
