This new release GIL Guide is giving information on the application of gas-insulated transmission lines (GIL) for voltages of 72.5 kV and above. This Guide is based on the IEC standard for GIL IEC 62271-204 where the technical requirements, type and on-site test for GIL are defined. 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.
The purpose of this guide is to provide technical assistance for the selection, application, and project management for a gas-insulated line (GIL) transmission project from initial planning through decommissioning and retirement.
The tutorial will give a short overview on the content of the new IEEE standard.
