Three-phase system has many advantages over single-phase system, which is as follows: 

(i) For a given dimension of the generator, three-phase machine produces higher power output than a single-phase machine. 

(ii) For the same capacity, three-phase alternator is smaller in size when compared to single phase alternator. 

(iii) Three-phase transmission system is cheaper. A relatively thinner wire is sufficient for transmission of three-phase power
