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 threephase short-circuit occurs at fault point F, obtain the fault MVA and fault current in \(\mathrm{kA}\) if the prefault busbar line-to-line voltage is \(13.2 \mathrm{kV}\). Choose 100 MVA as the base MVA for the system.
