Question

The voltage between __________ and ___________ is called phase voltage.

(a) line and line

(b) line and reference

(c) neutral point and reference

(d) line and neutral point

I have been asked this question in homework.

My question comes from Inter Connection of Three-Phase Sources and Loads topic in division Polyphase Circuits of Network Theory

Answer 1

Right option is (d) line and neutral point

The best I can explain: In a three phase four wire star connected system, the terminals R, Y and B are called the line terminals of the source. The voltage between line and neutral point is called phase voltage. And the voltage between line and line is called line voltage.
