Answer:
People think that if one phase has a voltage of 220V then 2phase voltage have 440V they are just sum it up but it wrong line Voltage is always √3 time of phase voltage in case of distribution system because all distribution system are in star. So Voltage L-L is near about 400V (230×√3~~400V)
