Taking 10% impedence of one gen.the faut level of one gen
will be 16000kva or 2.8KA at 415 Volts.the faut level for
eight generators will be 2.8x8=22.4KA

when neutral will carry the current?what could be the magnitude?

how to find 5 kilo meter long under ground 33 kv cable fault location if IR VALUE shows 0.05 M ohm @5000 volt.and cable fault locator shows some time fault distance 3 kilo meter ,3.7 kilo meter and some time 1 kilo meter? now how to find the fault location that where is leakage. note--it is tested with 5000 kv megger and insulation resistance is 0.05 M ohm. and some time 0.03 M ohm comes.
