11. A single-phase transformer has a voltage ratio on open-circuit of 3300/660-V. The primary and secondary resistances are 0.8 Q and 0.03 Q respectively, the corresponding leakage reactance being 4 Q and 0.12 Q. The load is equivalent to a coil of resistance 4.8 Q and inductive reactance 3.6 Q. Determine the terminal voltage of the transformer and the output in kW. [636 V, 54 kW]
