The single line diagram of power system is shown in Figure 4. The neutral of each generator is bolted grounded on a 100 MVA base. The data expressed in per unit on a common 100 MVA base is tabulated in Table 4. The generators are running on no load condition. Fault happened at bus 5. Calculate the fault current of single line-to-ground fault and line-to-line fault at bus 2 through a fault impedance Z;=j 0.15 p.u. G? ? 3 B T T T? T? 38010 Item G?
