1)The synchronous generator below has a 3-phase fault as shown. a. Graph the per unit fault current coming from the generator for the first 20 seconds(ignore DC offset). (Using Mathcad

or Matlab, plot the magnitude versus time) b. What is the fault current at 5 cycles (ignore DC offset)? Ans: 27.7 kA c. What is the asymmetrical fault current at 5 cycles assuming the generator X/R=100? Ans: 44.3 kA
