Example 32.19. The following data refer to a l-phase transformer : Turn ratio 19.5 1; R,= 25 2; X, = 100 ; R, = 0.06 2 ; X, = 0.25 Q. No-load current = 1.25 A leading the flux by 30°. The secondary delivers 200 A at a terminal voltage of 500 V and pf. of 0.8 lagging. Determine %3D by the aid of a vector diagram, the primary applied voltage, the primary p.f. and the efficiency.
