Choosing system bases to be \(360 / 24 \mathrm{kV}\) and 100 MVA, redraw the sequence networks for Problem 8.39.

Problem 8.39

The leakage reactance of a three-phase, 500-MVA, \(345 \mathrm{Y} / 23 \Delta-\mathrm{kV}\) transformer is 0.09 per unit based on its own ratings. The \(\mathrm{Y}\) winding has a solidly grounded neutral. Draw the sequence networks. Neglect the exciting admittance and assume American standard phase shift.
