IEEE Guide for Application and User Guide for Gas-Insulated Transmission Lines, Rated 72.5 kV and Above
Guidance for the planning, permitting, design, equipment specification, installation, commissioning, operation, and maintenance of gas-insulated transmission lines is provided in this project. Only technical aspects are addressed in this guide. Commercial and legal issues associated with gas-insulated transmission lines are not considered. This guide applies to ac transmission lines rated for maximum operating voltage of 72.5 kV and higher.
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No Superseded Standards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No Inactive-Withdrawn Standards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
