Fault level contribution by a generator.
Fault level contribution by a generator.
(OP)
We have a gen set consisting of a 5oo MVA generator and a 0.415/11 kV Traffo. The generator has Xd'= 15.9 %, Xd''= 11.1 %. The Traffo has z = 4.58%. I have calculated the fault level but its too high.
May be there is something I have forgotten and please remind me which of the generator reactances is appropriate
Thank you guys in advance.

Maybe it's 500KVA!!! Please see again Scotty's post.
