Consider a system with the one-line diagram shown below. The three-phase transformer
nameplate ratings are listed. The transformer reactances are given in percent: 10% = 0.1
p.u. The transmission line and load impedances are in actual ohms. The generator
terminal voltage (magnitude) is 13.2 kV (line-line).
A-B Transformer: 5 MVA, 13.2 kV/132 V, leakage reactance 10%
B-C Transformer: 10 MVA, 13.8 kV/69 V, leackage reatance 8%
Assume Sb=10 MVA.
Find the generator current, the transmission-line current, the load current, the load voltage, and the power delivered to the load.
