Answer / jagdish aher

single ph means RN,YN,BN&3ph means RYB each ph 120 degree
eletrically apart each other.it can be convertd into DC
form with the help of choppers.

Answer / sunil

Single phase is either YR or YB or BR where as 3 phase is
RYBN. To convert single phase to 3 phase multiply by 1.732.
i.e. root 3.

Single phase P = VI
Three phase P = 1.732 X V X I

Answer / pravin patil, amol, aher

Single phase means 230 V 50 Hz Power supply & 3 Phase means
415 V, 50Hz, For converting into another form like
mechanical or Heat Energy,Magnetic Energy.

In the solution of load flow eqation, Newton raphson method is superior to the gauss siedal method because (a)the time taken to perform one iteration in the NR method is less when compared to GS method (b)the number of iterations required in the NR method is more compared to that in the GS method (c)the number of iterations required is dependant on the size of the system in the NR method (d)convergence characteristics of the NR mehod are not affected by the selection of the slack bus
