voltage between the two terminals of a phase element
NOTE 1 – For star connection of a polyphase element which is connected to line conductors and to a neutral conductor, the phase-element voltages are equal to the line-to-neutral voltages.
NOTE 2 – For polygonal connection of a polyphase element which is connected to line conductors, the phase-element voltages are equal to the line-to-line voltages.
