--Star Circuit--

As for Phase Voltage = PVa to N
*which is always = 240V (on each phase)

As for Line Voltage = PVa to PVb
= 240 x 1.732 (square root of 3)
= 415V

*Line Voltage: The voltage present between any two of the
conductors in a three-phase system. It is 1.732 times higher
than phase voltage in a WYE connection.

*Phase Voltage: The voltage between any one conductor and
ground.
