A 150MW alternator generates an open-circut line-t0-line voltage of 12kV at nomial DC excitiation. When the terminals are placed in short-circuit the resulting current per phase is 8000A.

a) Calculate the approximate value of the synchronous reactance per phase.

b) draw the equivalent circuit of the alternator per phase under the DC field excitation conditions given above.

c) What is the nominal full load current per phase ?
