single phase voltage 230 and Three phase voltage 450 why 690 voltage
Answer Posted / prajapatsuraj306@gmail.com
Single phase differences are two phases 90 ' and Three phase differences are 120' and Three phase , Three wire ( R, Y, B,)
= sin 120+ sin120+ sin120
= 2.59
and Three phase Power
= 1.732 V I cos Q
= v I and cosQ is imagine part because they are value depand on circuit
= 2.59*1.732
= 450 volt
