Figure 8.26 shows a single-line diagram of a three-phase, interconnected generator- reactor system, in which the given per-unit reactances are based on the ratings of the individual pieces of equipment. If a three-phase short-circuit occurs at fault point F, obtain the fault MVA and fault current in kA, if the pre-fault busbar line-to-line volt- age is 13.2 kV.
