PC57.13
Standard Requirements for Instrument Transformers
To assist in the proper selection of Instrument Transformers this standard defines requirements for performance and interchangeability. Safety precautions are also addressed. This standard defines certain electrical, dimensional, and mechanical characteristics, and takes into consideration certain safety features of current and inductively coupled voltage transformers of types generally used in the measurement of electricity and the control. This standard defines the requirements for Class 1 instrument transformers. For instrument transformers of a nominal system voltage of 115 kV and above if Class 2 is required refer to IEEE Std C57.13.5(TM).
PC57.13-2016/Cor 1
Standard Requirements for Instrument Transformers - Corrigendum 1
This standard is intended for use as a basis for performance and interchangeability of equipment covered, and to assist in the proper selection of such equipment. Safety precautions are also addressed. This standard covers certain electrical, dimensional, and mechanical characteristics, and takes into consideration certain safety features of current and inductively coupled voltage transformers of types generally used in the measurement of electricity and the control.
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.

IEEE Standard Requirements for Instrument Transformers
Electrical, dimensional, and mechanical characteristics are covered, taking into consideration certain safety features, for current and inductively coupled voltage transformers of types generally used in the measurement of electricity and the control of equipment associated with the generation, transmission, and distribution of alternating current. The aim is to provide a basis for performance and interchangeability of equipment covered and to assist in the proper selection of such equipment. Safety precautions are also addressed. Accuracy classes for metering service are provided. The test code covers measurement and calculation of ratio and phase angle, demagnetization, impedance and excitation measurements, polarity determination, resistance measurements, short-time characteristics, temperature rise tests, dielectric tests, and measurement of open-circuit voltage of current transformers.
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.

C57.13.2-1986
American National Standard Conformance Test Procedures for Instrument Transformers
The purpose of this standard is to cover conformance test requirements for current and inductively coupled voltage transformers used for measurement and control functions in unit substations at primary system voltages above 600 V, but not exceeding 38 kV. The report describes relevant performance tests to demonstrate compliance with the applicable standards. The test specimen is normally subjected to all planned routine tests prior to the initiation of the conformance test program.
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
C57.13.2-1991
IEEE Standard Conformance Test Procedures for Instrument Transformers
Conformance test requirements are provided for current and inductively-coupled voltage transformers used for measurement and control functions in unit substations at primary system voltages above 600 V, but not exceeding 38 kV, except for those in certain installations as set forth in the standard. The selection of transformers for conformance testing, the basis for conformance, and the treatment of failures within a test sequence are covered. Impulse, voltage-withstand, accuracy, and temperature rise are specified. Insulation systems acceptance and production monitoring are considered
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
