Polyphase alternating current

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… WebNone of the previous polyphase alternating current transmission demonstration projects were on the scale of power available from Niagara: The Lauffen-Neckar demonstration in 1891 had the capacity of 225 kW Westinghouse successfully used AC in the commercial Ames Hydroelectric Generating Plant in 1891 at 75 kW (Single phase)
