which fault current is maximum: 3 phase short circuit, LG,
LL or LLG?? why??
in one of the problems that i have solved, 3 phase short
circuit current on an unloaded generator came out to be
less than the LG fault current. can anybody please explain
why.
Answer Posted / shubham gupta
it depends upon the grounding method employed.
LG fault current is more if the generator is solidly grounded.
