We can transfer power 2 or 3 or 4 phase but we know that
actually power generation is done in 3 phase it is economic.
If we want to transfer 4phase we should generate power from
different generators.
and i agree this answer
"AC change path called frequency having 0 to 360 degree and
all alternator phase sequence design at 120 degree
differences ie., 0/360 - 120 - 240 Degree universal in
3 phase sequence called R Y B."
