single line to ground fault
single line to ground fault
(OP)
While doing the arc flash study, I wonder what effect does the single line to ground fault has on arc flash current and incident energy?
When I performed the arc flash study, I did a mistake of low resistance grounding the transformer and generator instead of solidly grounding them. There was no effect on 3phase current. But single line to ground fault current changed drastically when I changed the grounding to solid. What effect does that have on arc flash?

Hi dpc...
I am using NFPA calculation. So is it going to change the arc flash. If not, why are we doing the single line to fault calculation?

Correct me if i wrong.
