2. One of the disadvantages of the IEEET1 exciter is following a fault the terminal voltage does not necessarily return to its pre fault value. Using PowerWorld Simulator case Problem 12_3 determine the pre-fault bus 4 terminal voltage and field voltage. Then use the simulation to determine the final, post-fault values for these fields for Ka = 100, 200, 50, and 10. Referring to Figure 1, what is the relationship between the reference voltage, and the steady-state terminal voltage and the field voltage? V SK 1+ST VIE V max V VR Ett 1 1+ST Fig 1.
