C57.12.10 for over 100MVA?

C57.12.10 for over 100MVA?

C57.12.10 for over 100MVA?

(OP)
I've seen some transformer specifications that use C57.12.10-1997, even though these devices are 167MVA and the referenced standard says it only goes up to 100MVA. I searched but could not find a similar standard at the same voltage classes for bigger transformers.

Anyone out there know whether [a] there is such a standard, and I just need to look a little bit smarter, or that C57.12.10 can be used even for bigger equipment.

Thanks in advance for any thoughts on this matter.

Hmm...

"Due to the fact that IEEE Transformers Committee members participating in the development of NEMA copyrighted C57 documents are not indemnified by NEMA... we find it necessary to cease our work on the following documents:

ANSI C57.12.10...."

Will continue looking...
