6. A 25 MVA, 13.2 KV alternator with solidly grounded neutral has a sub transient reactance of 0.25 p.u. The negative and zero sequence reactance are 0.35 and 0.01 p.u. respectively. If a double line-to-ground fault occurs at the terminals of the alternator, determine the fault current and line to line voltage at the fault. (May 2014)
