RE: generator fault current
For the start:
I3ph-fault=Inom gen/X"d (for the turbogenerator from 13%-17%).

RE: generator fault current
For 30MW 11KV Generator, rated current is 1968, Xd"(sat)-11.84% & Xd"(unsat)-14.79. i have to take saturation value or unsaturation value of Xd".
RE: generator fault current
You have use saturated transient X"d 11.84%
Regards and Good Luck.

RE: generator fault current
you informed as below
For the start:
I3ph-fault=Inom gen/X"d (for the turbogenerator from 13%-17%).
but i have still one doubt i,e I nom gen (or) V nom gen.
RE: generator fault current
It is Inom in ampere and X"d in %
So I3ph = 1968/(11.84/100)
