A30-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
