For the single line diagram shown which was solved previously with subtransient reactances in pu on \( 100 \mathrm{MVA} \) common base: Find the following by hand calculations and in 4 decimals: 1- The fault current, voltages at buses, line and generators currents and Thevenin's equivalent seen by the faulted during fault when a symmetrical three phase short circuit fault occurs at bus: i) 1 ii) 2 and iii) 3 4- Let the machine at bus 2 be a motor and find the interrupting current in breaker A shown for the fault at bus 3 5- if a line-end short circuit fault occurred on the line 1 - 2 near bus 2, find the subtransient fault current.
