The one-line diagram of a three-bus power system is shown in Fig. 12. Each generator is represented by an emf behind the transient reactance. All impedances are expressed in pu on a common 100 MVA base. Determine the fault current, the bus voltages, and the line currents during the fault when a balanced three-phase fault with fault impedance ${\mathrm{Z}}_{\mathrm{f}}=\mathrm{j}0.16$ pu occurs on bus 1 . Assume that all prefault bus voltages are $1.0\mathrm{pu}$. Fig. 12
