IEEE C37.122.4-2016

This project will provide guidance for the planning, permitting, design, equipment specification, installation, commissioning, operation, and maintenance of gas-insulated transmission lines. The guide will address technical aspects only. 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.

There is currently no complete guide covering planning, design, installation, and operation of gas-insulated transmission lines. The guide produced by this project will fill this void and become a useful reference for electric power engineers considering the installation of GIL.

New IEEE Standard - Active. 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.
