Superseded by IEEE Std C57.93-2007.This guide provides guidance and recommended practices on the installation and maintenance of liquid-immersed power transformers rated 501 kVA and above with secondary voltages of 1000 V and above. This guide covers the entire range of power transformers, including extra high voltage (EHV) transformers. This guide does not cover special transformers such as furnace transformers, rectifier transformers etc. Distinctions are made as required for various MVA ratings, voltage ratings, and types of liquid insulation.

C57.93-2019
IEEE Guide for Installation and Maintenance of Liquid-Immersed Power Transformers
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.
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.
