= 15: 1 6.) The following data refer to a single-phase transformer. Turns ratio 20:1. R. R, = 0,03; X, 60; X = 0,16. No load current = 1,5 A, leading the flux by 30°. The, secondary delivers. 150 A at a terminal voltage of 520 V and power 0,8-lagging. With the aid of a phasor diagram, determine: (a) The primary applied voltage; = 11 224,4) (b) the primary current; P(1= 8,9 A) (c) the primary power factor; (cos Ø = 0,728 lag.) -(d) the efficiency; (Eff. 85,8%) te) the percentage regulation.
