proove this answer for the following question

In the system shown in Figure W15, a balanced three-phase to ground fault occurs on bus 3. The generators each have an intrinsic reactance of 0.1 p.u. Impedances are given as p.u. on a 100 MVA base. 3 Figure W15 (i) Construct the admittance matrix of this system. 5 Marks] (ii)Determine the fault current in p.u. if there is no pre-fault current so that all bus voltages are originally at 1 p.u.
