C57.13.5-2003 - IEEE Standard of Performance and Test Requirements of Instrument Transformers of a Nominal Voltage of 115 kV and Above
Description: 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 standard also provides test procedures that were not adequately covered in the previous standard.
