Instrument Transformer References Help
(OP)
I've been asked to put together a talk for our line supervisors on proper selection of instrument transformers for metering and for relaying purposes. (It sounds like vendor reps are visiting them and getting them confused on the facts.)
I have some old books on inst. trfmrs that I can reference, but does anyone have a line on any good papers or newer reference books on this topic that I can look into?
Thanks for your help.

I don’t know if they’re intended as training materials, but ANSI C57.13-1993, C57.13.3-1993 and C12.11-1987 are baseline materials in instrument-transformer application.
GE’s GET-97D is old but most of it still applies. http://www.geindustrial.com/products/applications/GET-97D.pdf
ABB’s version is more glitzy but limited in scope.

1. IEEE Std 141-1993 (Red Book)
Section 11.8.1 Current Transformers
Section 11.8.2 Voltage (Potential) Transformers
2. ANSI/IEEE Std 242-2001 (Buff Book)
Chapter 3 "Instrument Transformers"
3. Since there is no voltage level indicated in the original posting, the high voltage, extra high voltage, etc. high voltage instrument transformer literature is avalable from the manufacturers. The book and paper treatment of those is somewhat scattered.
