A three-phase synchronous generator produces 10 MVA power under a rated voltage of 10 kV. Zero sequence component reactance of this generator is given as X0 = j0.1 pu, positive sequence component reactance X1 = j0.1 pu and negative sequence component reactance X2 = j0.1 pu, and the star point of this generator is given as Xn = j1 Ω grounded. a) Calculate the real value of the fault current that will occur in the three-phase short circuit fault at the output of this generator. (The actual value of the fault current will be calculated and entered AS INTENT (such as 3550.
