Correct....thanks David.
So to re-state my question....
Do I have to consider the VA rating of the upstream transformer that supplies the auto-transformer when doing the fault current calculation? Since there is a direct electrical connection to it; as well as to the auto-transformer.
Hi all...first post.
I am a journeyman electrician and I teach electrical apprentices. I have a question on how to calculate auto-transformer secondary fault currents.
I don't require engineering level calculations...just the concepts behind the calculation.
As I understand it an...
