2. For a given size of machine , the power generated in three phase alternator is three times the power generated in d.c. generator .Smaller size of machine make it cheaper
3. Generation of power at high voltage is easier in the case of a.c. than the case of d.c. generation.It is because of commutation problem in d.c. generation
4. For transmission of a given amount of power over a given distance at a given voltage , the conductor material required in the case of three phase a.c. system is less than conductor material required in two wire d.c. system
5.In case of 3 phase , 4 wire system two different voltages 230 Volt and 400 Volt can be obtained .Which is not possible in D.C. System
6. A.C. motors are simple in construction ,rugged and required less maintenance .These are comparatively cheap and smaller in size.
