Hi
draw the vector diagram for three phase balanced voltage or
current vectors.Then you will find why this 1.732 factor
comes.

1.732 is only for three phase vectors.

Answer / sanjana

line voltage is equal to sqrt of 3 the phase voltage and
that is line voltage=1.732 phase voltage

Answer / ariel

Line voltage = 2 * phase voltage * sin 180/ no. of phase

say 1 phase, 230v, what is the 3 phase voltage

line voltage = 2 * 230 * sin 180/3 = 400v
1.732 = 2*sin180/n
