IEEE Draft Guide for Application and User Guide for Gas-Insulated Transmission Lines (GIL), Rated 72.5 kV and Above

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.
