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.
