$($d$)$ A synchronous generator and a synchronous motor each rated $25$ MVA, $11$ kV having $15\%$ subtransient reactance are connected through transformers and a line as shown in Fig. $8($below$)$: The transformers $T_1$ and $T_2$ are rated $25$MVA,$\frac{11}{66}kV$ and $\frac{66}{11}kV$ with leakage reactance of $10\%$ each. The line has a reactance of $10\%$ on a base of $25$MVA,$66kV.$ The motor is drawing $15$ MW at $0\mathrm{.}8$ power factor leading and a terminal voltage of $10\mathrm{.}6$ kV when a symmetrical three$-$phase fault occurs at the motor terminals. Find the subtransient current in the generator, motor and fault.

Hint: Note here, generator and motor have their reactances on base MVA of $25$ MVA, similarly, line reactance is given at $25$ MVA. The voltage at motor bus before fault is $10\mathrm{.}6$ kV $.$
