Marks: +1, -0

Let V be the phase voltage of a three-phase, four-wire distribution system. What could be the line voltage of the system?

Solution:

The three-phase four-wire distribution system is star connected system.
For the star connected system, the line voltage is

√3

times the phase voltage.
Given phase voltage = V
Therefore, line voltage

= √3 × \V
