Guidance on and recommended practices for the installation and maintenance of liquid-immersed power transformers rated 501 kVA and above with secondary voltages of 1000 V and above are provided in this guide. The entire range of power transformers, including extra high-voltage (EHV) transformers are covered in this guide. Special transformers, such as furnace transformers, rectifier transformers, etc., are not covered in this guide. Distinctions are made, as required, for various MVA ratings, voltage ratings, and types of liquid insulation.

Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
PC57.93a
IEEE Guide for Installation and Maintenance of Liquid-Immersed Power Transformers Amendment: Cold Start of Power Transformers Filled with Natural Ester Liquids
The amendment mainly aims to recommend cold start methods of power transformers filled with natural ester liquids. The scope for the amendment is shown as follows: -- Requirements for properties of natural ester liquids under cold conditions. -- Cold start procedure of natural ester-filled power transformers. -- Liquid warming procedures. -- Operation requirements for the transformer's mechanically operated devices.
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
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.
No Superseded Standards
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No Inactive-Withdrawn Standards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
