    Split-phase electric power - Wikipedia

    • A split-phase or single-phase three-wire system is a type of single-phase electric power distribution. It is the alternating current (AC) equivalent of the original Edison Machine Works three-wire direct-current system. Its primary advantage is that, for a given capacity of a distribution system, it saves conductor material over a single-ended single-phase system. The syste… 展开

    Connections

    A transformer supplying a three-wire distribution system has a single-phase input (primary) winding. The output … 展开

    Balanced power

    In a so-called balanced power system, sometimes called "technical power", an isolation transformer with a center tap is used to create a separate supply with conductors at balanced voltages with respect to groun… 展开

    Applications

    In Europe, three-phase 230/400 V is most commonly used. 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 onl… 展开

    Railways

    In the electric power supply system of railways in Sweden split-phase electric power is also used on some railways. The center tap is grounded and one pole is fed to an overhead wire section, while the other wire is used for a… 展开
