Other Applications
Single phase AC powerlines of traction power networks are an example of a split-phase electric power systems. The voltage between the conductors of traction current power lines in Germany and Austria is 110 kV, with 55 kV between ground and conductor. The center tap of the transformer is grounded via a coil. In Sweden split-phase electric power is used for feeding the overhead wire of some railways. The center tap is grounded, one pole is fed with an overhead wire section, while the other wire is used for another section..
