Guidance on the use of outdoor power apparatus bushings is provided. The bushings are limited to those built in accordance with IEEE Std C57.19.00-1991. General information and recommendations for the application of power apparatus bushings, when incorporated as part of power transformers, power circuit breakers, and isolated-phase bus, are provided.

Recommended Practice for Routine Impulse Tests for Distribution Transformers
This recommended practice covers routine impulse tests performed on distribution transformers, as required in IEEE Std C57.12.00(TM), and described in 10.4 of IEEE Std C57.12.90(TM)-2021(1). Distribution transformers covered by this recommended practice are overhead, pad mounted, and underground liquid-immersed distribution transformers with requirements specified in IEEE Std C57.12.20, IEEE Std C57.12.23, IEEE Std C57.12.24, IEEE Std C57.12.34, IEEE C57.12.36, IEEE Std C57.12.38 and IEEE Std C57.12.40. This recommended practice covers only those aspects of impulse testing that are specific to routine testing of distribution transformers. For more thorough coverage of impulse testing of transformers in general, IEEE Std C57.98(TM) should be consulted.
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
IEEE Recommended Practice for Routine Impulse Tests for Distribution Transformers
General test procedures for performing routine quality control tests that are suitable for high-volume, production line testing are included in this recommended practice. Transformer connections, test methods, circuit configurations, and failure detection methods are addressed. This recommended practice covers liquid-immersed, single- and three-phase distribution 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.

IEEE Guide for Transformer Impulse Tests
Transformer connections, test methods, circuit configurations, and failure analysis of lightning impulse and switching impulse testing of power transformers are addressed. This guide is also generally applicable to distribution and instrument transformers.
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.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
