IEEE C37.123-2023 PDF

This guide is for the development of specifications for the technical requirements for the design, fabrication, testing, installation, and in-service performance of a high-voltage gas-insulated substation (GIS). This document is issued as a guide for use in compiling procurement specifications for the design, fabrication, testing, installation, and in-service performance of high-voltage GIS equipment. This guide applies specifically to all types of high-voltage GIS equipment rated above 52 kV ac. The imperative mode of the language is illustrative of that used in design and procurement specifications. It does not imply that this document is anything other than advisory in its scope. Specifically, this revision will align the text with IEEE Std C37.122™ and IEEE Std C37.122.1™. Revision Standard - Active. The development of specifications for the technical requirements for the design, fabrication, testing, installation, and in-service performance of a high-voltage gas-insulated substation (GIS) are covered in this guide.
