A transformer with turns-ratio 8:1, has the resistances of the primary and secondary windings as 0.85 Q and 0.012 Q respectively, and the leakage reactances as 4.8N and 0.07 O respectively. Determine the voltage to be applied to the primary to obtain a current of 150 A in the secondary when the secondary terminals are short-circuited. Ignore the magnetizing current.
