Ex. 1500 3phase pad, 480Y/277, with 5.75% IMP.
(((((1500*1000)/3)/480)*1.732)*100)/5.75=31377 Fault Current
Hope this helps

1. Impedances of the three transformers.
2. Equivalent short circuit impedance of the system connected to the primary of the transformers.
3. Impedance of any series reactors (if any).
4. Are the three transformers operated in parallel on the secondary side?
