State of the Art of Instrument Transformers
The WG launched by SC 12 (Transformers) in the mid-90s, and later transferred in 2002 to SC A3, has completed this state of the art of Instrument Transformers at the start of the 21st century a few years ago, without publishing a formal report. It has been felt that the results, of significant value for designers and users, deserve publication as a TB.
