How to determine short circuit capacity of power transformer
(OP)
Hello,
I am working with a 5 MVA oil filled transformer, and I am trying to figure out how to fuse the equipment on the secondary side in order to properly protect the transformer against short circuit damage. I am looking for documentation which will help me to determine the magnitude and duration of the allowable fault current based on the ratings of the transformer. Can someone point me in the right direction on this?

There are many in this group that could answer your question but I doubt if any one will. Sorry.

Abstract
The protection of power transformers is covered; various electrical protection schemes are explored; and guidelines are given for the application of these schemes to transformers. Alternative detection methods including mechanical, thermal, and gas analysis are discussed.

Then again you can put very little protection, and buy insurance.

Thanks. The damage curves are what I was looking for.
