A three-phase, 10-MVA, 4.16-kV generator with sub transient reactance X_dʺ = 20% feeds a three-phase, 1-MVA, 4.16 kV/480 V transformer with X_trfr = 5% via a cable that has the leakage reactance X_cable = 2 mΩ/phase as shown below. Neglecting all resistances, determine the symmetrical rms and the worst-case first offset (asymmetrical) peak current in a three-phase fault at the transformer output terminals using: 

(1) All reactance values in percent and 

(2) All reactance values in ohms.
