In star connected stator the line voltage is equal to
1.7321 times the phase voltage, but in case of the Delta
connected stator the line voltage is equal to phase voltage
as we done the calculation of poly phase balanced and
unbalanced networks.
the relation between the phase voltage in star connecred
stator to delta connected stator is,

Delta connection: Vline = Vphase ------(1)
Star connection: Vline = 1.7321 X Vphase-----(2)
from equation (1) & (2)

Vph(Delta) = 1.7321 X Vph(Star)
