IEEE Standard of Performance and Test Requirements of Instrument Transformers of a Nominal Voltage of 115 kV and Above

This standard covers the test requirements, including test sequences, criteria, methods, and documentation for instrument transformers of 115 kV nominal system and above. It is to be used a supplement to IEEE STD C57.13-1993. Besides the provision of up-to-date test requirements, the trial-use standard also provides test procedures that were not adequately covered in the previous standard.
