Question { 10681 }

Why we use three phase world wide why not four phase or
five phase being used?


Answer

it is world wide standard.Thats why we use three phase
system.but its not so much logical answer.i think another
reason.we are producing electricity by alternator.so when we
use four or five phase system we have to change the design
of alternator.Then we should change pole,winding
everything.That is may be totally unbalanced.and if it is
possible it will not be cost effective.so we use three phase
system
