I am doing a coordination study, involving a 750 kva 12.47-480/277 volt transformer, with primary current-limiting fuse protection, in this case an EJO-1 fuse.
I have never been clear on "how far up" the transformer damage curve I have to protect with the fuse. Is there something in the standards that covers this?
Thanks.
