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


A 3-phase, 10 MVA, 11 kV generator with a solidly earthed neutral point supplies a feeder. The relevant impedances of the generator and feeder 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
(i) the magnitude of fault current

(ii) line to neutral voltage at the generator terminal
