Three phases can be connected either in star (Y) or as
Delta (Δ). In star connection the line and phase currents
are one and the same. But the line to line voltage is
square root of 3 times the voltage between a line
(or phase) and the neutral.In domestic connections a
wire from the neutral and any one of the phases are
brought in.
Therefore, in Delta connection V (Phase) = V (Line) = 240
in INDIA
In Star connection V (Line) = Sqaure root 3 of V(Phase) =
415 in INDIA
