If 1-phase voltage is 220V, why is 3-phase 440V and not 660V ?

If 1-phase voltage is 220V, why is 3-phase 440V and not 660V ?
Last Answer : Phase voltage =220v /( phase to neutral) Line voltage = 380 v ( phase to phase) Phase angle difference 120° So when two phases reach vmax +ve I.e. (+220v) + (+220v) = 440v that time due ... these event happen very fast. Hence we have 440 v only in three phase motor. √3.phase voltage= 380 v.
