WHY WE CAN GENERATE POWER IN 3PHASE MODE ONLY NOT IN 4 OR
5PHASE
Answer Posted / sudhir
for 4 phase system ,phase difference b/w phase 0,90,180,270
deg.at every instant 0deg phase cancil by 180 deg phase,and
90deg phase cancil with 270 deg phase . and two conductor
work as phase and two for return path so it work as two
circuits of two phase supply and there are lot of advantages
of three phase supply over two phase supply.if we need of
two phases then it is simply generated by three phase.
and three phase system is symmetrical(line voltage or
current in magnitude between any two phases is equal to
other two phases in balance condition ) but 5 phase circuit
is not symmetrical.so calculation and operation is difficult.
as we increases the phases the fluctuation of torque in case
of polyphase induction motor is reduses.so 6-phase motor is
bater then 5-phases motor and 6 phase supply
simply can obtains by 3 phase supply so why we generate 5 phase
supply.
