A 3-phase, 10 MVA, 11 kV generator with a solidly earthed neutralpoint supplies a feeder. The relevant impedances of the generator andfeeder in ohms are as under:

                                          Generator     feeder
Positive sequence impedance     j 1.2          j 1.0
Negative sequence impedance   j 0.9           j 1.0
Zero sequence impedance         j 0.4          j 3.0

If a fault from one phase to earth occurs on the far end of the feeder, calculate

(1) the magnitude of fault current
2) line to neutral voltage at the generator terminal.
