Beginner Question: Ground Fault Current
Beginner Question: Ground Fault Current
(OP)
I have a beginner type question on ground fault current. I am reading Chapter 4 of Electric Power Distribution Equipment and Systems where it says, "Ungrounded primary connections do not supply ground fault current to the primary distribution system...Grounded wye primaries may provide an unwanted source for ground fault current"
From what I understand, ground fault current is caused by an unintended path to ground (i.e. a line-to-ground fault). I think my confusion lies in the wording of supply and source. What is meant by "do not supply ground fault current..." and "source for ground fault current"?
Thanks

Conversely, you might have a source of ground current, but without an unbalanced load or a line-to-ground fault, no current would flow from the source.

If there was no electricity there would be no internet. Good point, don´t you? :D
