3. The positive, negative and zero sequence reactances of a 20 MVA, 13.2 kV synchronous generator are 0.3 pu, 0.2 pu and 0.1 pu respectively. The generator is solidly grounded and is not loaded. Neglect all resistance. Determine the fault current if a double line to ground fault occurs at the generator terminals b and c.
