IEEE C57.13.5-2003

This standard applies to new single-phase instrument transformers of 115 kV nominal system voltage and above with capacitive insulation system for line-to-ground connection and for both indoor and outdoor application. It is intended for use as a supplement to IEEE Std C57.13 and as a basis for performance and safety of equipment. It also describes test sequences, criteria, methods and documentation for the tests.

This standard is intended to provide supplement to IEEE Std C57.13 on: a) Up-to-date test requirements and sequence and b) Refinements of certain performance requirements and clarification of test procedure, documentations

New IEEE Standard - Superseded. 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.
