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

Answer / karun

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

Answer / kumaresan r

R Y B OR 3 PHASE R N , Y N , B N, OR SINGLE PHASE R Y , BY , YB TWO PHASE ............................................................................................

Answer / simon

There is a device namely alternator/Genrator (big size) which genrates 3 Phase supply i.e R,Y,B in max of 11000v or 11kv only in India. Hense the multiple will b always in 3.

I know during Surge Impedance Loading maximum power is transferred through a transmission line and also Sending end voltage becomes equal to Receiving end voltage i.e Vs=Vr so my question is if both end voltages are equal then how current travels in such line hence how power is transmitted because flow of current needs Potential difference??
