Since there are 60 coils in each phase and 8 turns per coil, all connected in series, there are 480 turns per
phase. The resulting voltage is
V   2N P k p k d f e  2 480 turns 0.951 0.962  60  Hz 
V   117 , 061 

The phase voltage of this generator must be 13 8 . kV / 3  7967 V , so the flux must be

7 967 V
   . 0 068 Wb
