The leakage reactance of a three-phase, \(300-\mathrm{MVA}, 230 \mathrm{Y} / 23 \Delta-\mathrm{kV}\) transformer is 0.06 per unit based on its own ratings. The \(\mathrm{Y}\) winding has a solidly grounded neutral. Draw the per-unit equivalent circuit. Neglect the exciting admittance and assume the American Standard phase shift.
