Two-phase electrical power was an early 20th-century polyphase alternating current electric power distribution system. Two circuits were used, with voltage phases differing by one-quarter of a cycle, 90°. Usually circuits used four wires, two for each phase. Less frequently, three wires were used, with a common wire with a larger-diameter conductor. Some early two-phase generators had two co… WebTesla developed polyphase alternating current systems of generators, motors and transformers, eventually holding 40 basic US patents. These were bought by George Westinghouse, who was determined to supply America with the Tesla system, which eventually won out as the superior technology and became the standard power in the 20th …
