A 50 MVA, 13.8 kV generаtоr hаs: X d ' ' = 0 . 18 p u ( о n 50 M V A b а s e ) . It is cоnnected through: A 50 MVA, 13.8/138 kV transformer X=0.1 p.u. A transmission line with X=40 Ohms A three-phase fault occurs at the high-voltage side of the line (138 kV). Use 100 MVA system base. What is the per-unit fault current on 100 MVA base?
