IEEE C57.13.5 2009 Edition, September 11, 2009 Performance and Test Requirements for Instrument Transformers of a Nominal System Voltage of 115 kV and Above
More info
Description / Abstract:
This standard applies to 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.
This standard is intended for use as a supplement to IEEE Std C57.13™-20081 and as a basis for performance and safety of equipment. It also describes test sequences, criteria, methods and documentation for the test.
Purpose
The purpose of this standard is to supplement the IEEE Std C57.13-2008, with specific requirements to 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 applications.
1 Information on reference can be found in Clause 2.
