Standard Details
Single-phase instrument transformers of a nominal system voltage of 115 kV and above with capacitive insulation system for line-to-ground connection and for both indoor and outdoor application are discussed in this standard. This standard is intended for use as a supplement to IEEE Std C57.13™-2008 and as a basis for performance and safety of equipment. It also describes test sequences, criteria, methods and documentation for the test.

| Existing Standards |
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.
