One supply phase (phase-to-neutral) from the utility is converted to split-phase for the customers. In electrical engineering, single-phase electric power (abbreviated 1φ) is the distribution of alternating current electric power using a system in which all the voltages of the supply vary in unison. Single-phase distribution is used when loads ...
single-phase electric power An alternating current power system using only two wires, where peak voltages in each wire occur at the same time. single-sideband modulation A radio carrier modulation system where redundant frequencies of one duplicate side band are filtered out along with the carrier, to save transmitter power. skin effect
Phase space formulation, a formulation of quantum mechanics in phase space; Phase (waves), the position of a point in time (an instant) on a waveform cycle Instantaneous phase, generalization for both cyclic and non-cyclic phenomena; AC phase, the phase offset between alternating current electric power in multiple conducting wires
A steam turbine used to provide electric power. An electric power system is a network of electrical components deployed to supply, transfer, and use electric power. An example of a power system is the electrical grid that provides power to homes and industries within an extended area.
However, 130/225 V, three-wire, two-phase electric power discontinued systems called B1 are used to run old installations in small groups of houses when only two of the three-phase high-voltage conductors are used. The phase shift in Europe is 120°, as is the case with three-phase current. That's why we calculate 130V * √3 = 225V.
In power engineering, a single-line diagram (SLD), also sometimes called one-line diagram, is a simplest symbolic representation of an electric power system. [1] [2] A single line in the diagram typically corresponds to more than one physical conductor: in a direct current system the line includes the supply and return paths, in a three-phase ...

In northern and central Europe, residential electrical supply is commonly 400 V three-phase electric power, which gives 230 V between any single phase and neutral; house wiring may be a mix of three-phase and single-phase circuits, but three-phase residential use is rare in the UK.
