A $100$MVA, $13\mathrm{.}8$kV$,$ Y$-$connected, $3$phase $60$Hz synchronous generator is operating at the rated voltage and no load when a $3$phase fault occurs at its terminals. Its reactance per unit to the machines own base are Xs$=1\mathrm{.}00,$ X$\text{'}=0\mathrm{.}25,$ X$"=0\mathrm{.}12$ And the time constant are: T$\text{'}=1\mathrm{.}10,$ T$"=0\mathrm{.}04$s$.$ The initial DC Component in this machine averages $50\%$ of the initial AC Componen.

i$.$ What is the AC component of current in the generator the instant after the fault.

ii$.$ What is the total currAC$+$DC$)$ in tHhhh
