Editing Three-phase electric power (section)

==Terminology==
The [[electrical conductor|conductors]] between a [[voltage source]] and a [[electrical load|load]] are called lines, and the [[voltage]] between any two lines is called '''line voltage'''. The voltage measured between any line and neutral is called '''phase voltage'''.<ref>{{cite book | last = Brumbach | first = Michael | title = Industrial maintenance |page=411 | publisher = Delmar, Cengage Learning | location = Clifton Park, NY | year = 2014 | isbn = 9781133131199 }}</ref> For example, in countries with nominal 230 V power, the line voltage is 400 V and the phase voltage is 230 V.  For a 208/120 V service, the line voltage is 208 V and the phase voltage is 120 V.
