Rework Example 3.5; using \(\mathrm{S}_{\text {base } 3 \phi}=100 \mathrm{kVA}\) and \(\mathrm{V}_{\text {baseLL }}=600\) volts.

Example 3.5

As in Example 2.5, a balanced-Y-connected voltage source with \(E_{a b}=480 \angle 0^{\circ}\) volts is applied to a balanced- \(\Delta\) load with \(Z_{\Delta}=30 / 40^{\circ} \Omega\). The line impedance between the source and load is \(Z_{\mathrm{L}}=1 / 85^{\circ} \Omega\) for each phase. Calculate the perunit and actual current in phase \(a\) of the line using \(\mathrm{S}_{\text {base3 } \phi}=10 \mathrm{kVA}\) and \(\mathrm{V}_{\text {baseLL }}=\) 480 volts.
