Basic information on Gas Insulated Transmission lines (GIL)
2008 IEEE Power and Energy Society General Meeting - Conversion and Delivery of Electrical Energy in the 21st Century, 2008The GIL is a transmission system for the transmission of high power levels over long distances, to solve specific routing or access problems, or as connections in power plants, and substations. Current ratings of 4000 Amps or more per circuit and distances of several kilometers are possible.

Application of the world's longest gas insulated transmission line in Japan
Proceedings of the 7th International Conference on Properties and Applications of Dielectric Materials (Cat. No.03CH37417), 2004In this paper we describe the SF/sub 6/ gas insulated transmission line (GIL) applied to the 275 kV Shinmeika-Tokai line, which is designed to transport 2,850 MW in a 3.3 km tunnel. To transport this large electric power, two circuits are needed for GIL.

Metallic particles in DC gas-insulated transmission lines
Journal of Physics D: Applied PhysicsAbstract Metallic particles have a significant influence on the insulation reliability of DC gas-insulated transmission lines (GILs). This paper first outlines metallic particles in GIL, predominantly in spherical, linear-like, and dust forms, from the perspectives of electrodynamic forces and motion characteristics. Then, the mechanisms

Management of gas-insulated transmission lines magnetic fields
11th International Symposium on High-Voltage Engineering (ISH 99), 1999Recent worldwide attention to the harmful effects of magnetic fields emanating from power lines resulted in a growing motivation to develop methods for magnetic field mitigation aiming at reducing the possibilities of such hazards. In densely populated areas, gas-insulated transmission lines or cables offer an attractive alternative to overhead ...

Magnetic fields around gas-insulated transmission lines crossing
2001 Power Engineering Society Summer Meeting. Conference Proceedings (Cat. No.01CH37262), 2001Gas-insulated transmission lines or cables (GITL), owing to their compact nature, offer an attractive alternative to overhead transmission lines where space is limited, such as in densely urban areas. Consequently, it is important to address the issue of power frequency magnetic fields emanating from GITL because of concerns that exposure to these ...

Gas insulated transmission lines (GIL): ready for the real world
2000 IEEE Power Engineering Society Winter Meeting. Conference Proceedings (Cat. No.00CH37077), 2002Gas-insulated transmission lines (GIL) are a further development of the tubular conductor intended for long distances and are especially suitable for connecting conurbations to centers of power supply. They are also as "invisible" as ordinary power cables as well as having a number of other advantages.

Steady state and transient ampacities of gas-insulated transmission lines
11th IEEE Mediterranean Electrotechnical Conference (IEEE Cat. No.02CH37379), 2003This paper presents a thermal model for predicting the steady state and transient ampacities of gas-insulated transmission lines (GILs). Using the thermal model, a computer program has been formulated such that it can estimate the ampacity of a GIL for any time-varying or constant current loading and any variation in environmental conditions.
