Answer Posted / baskaran.r
in a given frame size we can get any number of phases but 3
phases are high in utilizing the capacity without much
complications. in a 3 phase system the phases are separated
by 120 degrees. in a two phase system the angle between them
will be 180 degrees which is the same as single phase only.
