 That same year, Westinghouse formed the "Westinghouse Electric & Manufacturing Company"; in 1889 he renamed it as "Westinghouse Electric Corporation".The Westinghouse company installed 30 more AC-lighting systems within a year and by the end of 1887 it had 68 alternating current power stations to Edison's 121 DC-based stations.This competition with Edison led in the late 1880s to what has been called the "war of currents" with Thomas Edison and his company joining in with a spreading public perception that the high voltages used in AC distribution were unsafe.
