A three-phase power system is fed from the secondary of a A-Y connected transformer, with a neutral grounded through an impedance of j1 pu. The transformer series impedance is j0.15 pu. The transmission line impedance is jo.2 pu, with no zero sequence component. The sending end voltage is assumed to be 1 pu. The load is a Y-connected impedance of 1 pu (resistive). If a short circuit occurs at the load end, with a grounding impedance of 0.1 pu, calculate the fault current for a: (a) Three-phase fault (b) Single-line to ground fault (c) Line-to-line fault (d) Double-line to ground fault
