phase to phase displacement is 120degree and magnitude
same.but nutral voltage is zero

the difference is given by under root of 3 becoz wen supply
is differntiated den the phase difference becomes the root3

 Is This Answer Correct ? 9 Yes 2 No

phase to phase displacement is 120degree and phase to phase
means the system is in delta connection.where as phase to
neutral means the system in star connection.in this star
connection phase to neutral voltage is 440/1.732(Root
3),i.e., single phase connection.

It happens due to ohms value of the copper/aluminum conductor of the winding. The ohmic value of phase to neutral is less than phase to phase. Total impedance of the circuit, Z=root of R square+ XL square
