I’m looking for a fault calculator to download (buy) to calculate standard utility transformers such as 667KVA 7200/12470- 277 V 3%Z transformers single or three phase
Any info would be welcomed

the formula can't get any simpler.
Max. SCC in amps for a xfmr =FLA/Z
where Z is in per unit. (3%=.03pu)
You can set up a spreadsheet for this calculation.
In fact it takes less time to calculate it on a calculator, then the time it takes to open a excel program on a PC!!
