why do we generate only 3ph ac?is it possible to generate
4ph,5ph,....?
Answers were Sorted based on User's Feedback
In Single Phase the Voltage or current will be Zero for
every Half Cycle
In Two Phase the Votage or current in one phase is zero and
at the same time other phase also zero and one phase get
peak and other also get peak becuase the phase diffrence is
180Dec. so here also no votage of current if one is zero.
In Three Phase the Phase diffrence between phases is 120Dec
so that if one phase is zero rest of two will get some
magnetude.So here we get Voltage or current if any one
phase is zero.
So there is no need to generate 4phase and 5phase systems

Answer / mohan raj
yes,we can also generator 4ph ,5ph,... AC but it very expensive
At the mean time transmission losses in india is above 27%
of power generation at 3ph AC.
let thick about losses,no.of conductor, generator &
transformer design & manufacturing cost all those thicks.
finally in india not possible generate 4ph ,5ph,...

Answer / vinay
i want to ask how we can generate 4 phase ac i think in 3 phase thr is equal phase difference between all the phases...how can we achieve this in 4 phase ac supply but yes we can produce 6 phase 9 phase...supply

Answer / dhiren
mostly we use 1ph and 3ph and 6ph , 3ph line we can use it
as a 1ph or 3ph and also as a 6ph . so as per requirement
mostly generation is been done 3ph .
yes , generation of any phase can be done but we generate
which we required.
3ph is suitable for all so ....

BECAUSE THE 3 PHASE SYSTEM FOUND TO BE THE MOST ECONOMICAL
FROM OTHER TRANSFOMATION , IN SINGLE PHASE THERE WILL
ALWAYS BE MAGNETIC FORCES TRANSFORMER WALL WILL ALWAYS BE
HEATED, IN 2 PHASE SYSTEM IF A WIRE BREAK HAPPENS HALF OF
THE LOAD WILL BE DISCONECTED NOT LIKE THE 3 PHASE, AND IN 5
OR 4 PHASE THERE WILL BE ALOT OF WIRES CONNECTION AND
ISOLATORS USED WICH IS NOT ECONOMICAL

Answer / sjf
yes,we can also generator 4ph ,5ph. But phase angle also
change like 90, 72 degrees.
