Thanks very much for the vote of confidence, folks. One more link on instrument transformer basics at:

http://www.abb.com/GLOBAL/ABBZH/ABB...EC96AC155B585256A47005E8FE7/$file/IT+Book.pdf

{May need to 'cut and paste' this link to get it to work.} It contains a number of references to ANSI/IEEE C57.13--the principal Instrument Transformer standard in the US.

Great references!
I would also recommend a book "INTRODUCTION TO INSTRUMENT TRANSFORMERS" by Brian D. Jenkins and published by George Newnes Ltd. in 1967 (rather old!).
