A Y-connected synchronous generator rated \(20 \mathrm{MVA}\) at \(13.8 \mathrm{kV}\) has a positive-sequence reactance of \(j 2.38 \Omega\), negative-sequence reactance of \(j 3.33 \Omega\), and zero-sequence reactance of \(j 0.95 \Omega\). The generator neutral is solidly grounded. With the generator operating unloaded at rated voltage, a so-called single line-to-ground fault occurs at the machine terminals. During this fault, the line-to-ground voltages at the generator terminals are \(V_{a g}=0, V_{b g}=8.071 \angle-102.25^{\circ}\), and \(V_{c g}=8.071 \angle 102.25^{\circ} \mathrm{kV}\). Determine the sequence components of the generator fault currents and the generator fault currents. Draw a phasor diagram of the prefault and postfault generator terminal voltages. For this fault, the sequence components of the generator fault currents are all equal to each other.
