Referring to the below figure, a symmetrical three-phase short circuit fault occurs at Point F. The parameters of the equipment are shown below. Generator (G): II kV, 50 MVA, 15% Transformer 1 (T1): 11/132 kV, 10 MVA, 10% Transformer 2 (12): 11/132 kV, 10 MVA, 5% Using 100 MVA as the base MVA, determine: Ref. PC-3 (a) (b) (c) (d) (e) (f) (g) (h) (0) ++ (1) the per unit impedance of Generator (G); the per unit impedance of Transformer (T1); the per unit impedance of Transformer (T2); the per unit equivalent impedance of the system; the fault level in per unit value; the fault level in the unit MVA; the fault current in the unit Ampere; (2 marks) (2 marks) (2 marks) (2 marks) the base impedance (2b) at the 11 KV busbar; and (2 marks) (2 marks) (2 marks) the reactance of the reactor in per unit value if a reactor is added in between the generator G and the 11 kV busbar so that the fault level is limited to 50 MVA; (2 marks) (2 marks) the reactance of the reactor in Ohms (0) if a reactor is added in between the generator G and the 11 kV busbar so that the fault level is limited to 50 MVA.
