WHY WE CAN GENERATE POWER IN 3PHASE MODE ONLY NOT IN 4 OR 5
PHASE?
Answers were Sorted based on User's Feedback
3 phase power is the most economical solution.
Firstly as the number of phases increase accordingly the
number of conductors, insulators etc will increase which
will be costlier. And secondly as number of phases increases
power does not increase linearly i.e. total power supplied
in N phase system is not equal to N(power supplied by single
phase).It is their vector addition. Power v/s phase graph
will take a shape like the saturation curve of transformer
core. So at higher phases cost wise input is high but power
wise output is not that high.
That's why 3phase system is the optimum solution

compared to all the a.c system the conductor volume is less and practically it is adopted same system and more reliable

Answer / pavanchoudhary
we generate in 3 phase instead 4&5 phases as co-terminal angle of resultant vector cancles instead we go head for 6 phases since by by tilting one of 3 phase transission line by 60 degrees we can pose into first 3phase line so same circumference now propagating double power but it loses linearity when move to 12 phase accampained with sophisticated network as 3phase line require 3 circuitbreakers and 3 busbar at substation 6phases requires 6 C.B & busbar

Answer / upendrae
according to the 3-phase alternating current the phase
diffrence for each phase must be 120 deg.if we consider the
3 phase,we get the total of 60 deg for one complete
cycle.thats why we allways generate the power in three phase
only

Answer / vinod.t(sathavahana ispat ltd)
a 3 phase system is an arrangement of three winding
producing 3 single phase voltages of the same magnitude and
frequency but displaced 120 degree electrical from one
another the 3 winding are connected in such a way that 3
voltages act simultaneously in the circuit,each supplying
power at different intervals of time to a comman load.

Answer / s ramar
Magnitude of Phase-to-phase (line) voltage is same
irrespective of whichever two phases you select.

Answer / ahmed.adel
in the mathematical solution any 3 forces are equaled in
magnitude and shifted with each one with 120 degree the
equivalent is equal to zero so we could have line that
called nuteral.the capability in 3 phases only the voltage
to neutral and line to line voltage

Answer / irfan khan
because , for balance 3 phase system the phase difference
must be 120 digree electrical and the AC complete one cycle
in 360 digree. so for balance system ganerates 3 phase
power.

why rotor resistance starter is not suitable for squrielcage induction motor?why it is suitable for slipring induction motor?
after parallaing two generators current is shooting up in both the generators.for ex: load is 400 kw..after paralling and load sharing current in running gen is approx 900 amps and incoming is 750 amps which is too high when trying toshift the load current in incoming gen is coming more than 1300 amps and both getting tripped and making blackout..

what current is taken from a double wound 500kva transformer
Is there a possibility to use such a treshold voltage for the NMOS part of a CMOS circuit that during the switching it will start conducting only after the PMOS part will be already closed, by this eliminating the leakedge current? Please note, I'm not asking about the well bias in standby mode, but about the "antileakedge" measures during normal operation.

Active power= VI COS FI But incase of leading power factor ( more than unity), may we use other formula ? because the cos fi (value of cos thita) should not be grater than one.
In case of generator when we consume more power produces by it why load on generator increase and starts sound more. and how it is adjusted..
