Consider two three-phase transformers, the first transformer has a delta connection on its primary side and a wye connection on its secondary side; whereas, the second transformer has a wye connection on its primary side and a delta connection on its secondary side. Eachtransformer is specified by Xeq=0.43Ω and N2/N1=17. Find the generator current, transmission line current, load voltage, and the complex power delivered by the load.
A-B Transformer: 5 k VA, 400 V/1.2 kV, leakage reactance 5%(Xeq=0.05 p.u.)
B-C Transformer: 6.7 kVA, 1200 V/120 V, leakage reactance 4%(Xeq=0.04 p.u.)
The line in circuit B has an impedance of j200Ω. The load in circuit C operates at 5+j2Ω.
