Consider the single-line diagram of a power system shown in Figure 3.42 with equipment ratings given:

Choose a base of 100 MVA for the system and \(132-\mathrm{kV}\) base in the transmission-line circuit. Let the load be modeled as a parallel combination of resistance and inductance. Neglect transformer phase shifts. Draw a per-phase equivalent circuit of the system showing all impedances in per unit.
