B) line voltages.

Question

Quizplus · Accepted Answer

When we refer to the voltage rating of a transmission or distribution line, we are referring to the line voltage, which is the voltage difference between the two conductors of the line. The phase voltage, on the other hand, is the voltage difference between a single conductor and the neutral point in a three-phase system.
