Answer / engr. l. o. osuji

Hi,
Voltage by definition is the potential difference between
two points e.g phase-neutral is 230V and line-line is 440V
according to you. You cannot measure the voltage of a line
alone. If, however, you insist on measuring the voltage of
the line alone your result will be zero. It must be between
the line and something else.

I jst wnt to add something in previous answer.In AC System
all three phases are 120 degrees apart & if u take vector
sum of it u will get 0.Hence it follows KVL.
Vector Vr+Vector Vy+Vector Vb=0.
