A 30-kVA 8000/230-V distribution transformer has an impedance referred to the primary of 20 + j100 Ω. The components of the excitation branch referred to the primary side are RC =100 kΩ and XM =20 kΩ (a) If the primary voltage is 7967 V and the load impedance is ZL= 2.0 + j0.7 Ω. what is the secondary voltage of the transformer? What is the voltage regulation of the transformer? (b) If the load is disconnected and a capacitor of –j3.0 Ω is connected in its place, what is
