Applications of Gas Insulated Transmission Lines (GIL)
2008 IEEE Power and Energy Society General Meeting - Conversion and Delivery of Electrical Energy in the 21st Century, 2008This paper discusses the direct buried systems in the Hudson Generation station in NJ, Extensive tunnel installations of a SF6/N2 GIL in Geneva and development test installations for direct buried SF6/N2 GIL designs. The following examples show other applications: connections in power plants, line or transformer connections in gas insulated substation,

Induced Current Estimation Algorithm of Gas Insulated Line
2018 15th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON), 2018This paper presents the analysis of induced voltage and induced current in enclosure pipe of three-phase gas-insulated transmission line. The induced current and induced voltage are carried out so that generalized mathematical model can be obtained. The current is derived based on electromagnetics theory.

Operating Parameters of Compressed-Gas-Insulated Transmission Lines
IEEE Transactions on Power Apparatus and Systems, 1969This paper describes a method to choose the physical parameters of a compressed-gas-insulated cable. A calculation of the power rating, losses, and critical length is carried out based on the physical parameters. This calculation is then compared with the ratings of pipe-type cable and is shown to be superior particularly for high-voltage, high-power ...

Heat insulating properties of a multilayer solid-gas lining
Refractories and Industrial Ceramics, 2008The properties of a multilayer lining consisting of alternating solid and gaseous layers are studied. The role of heat radiation and heat conduction through the gas-solid lining is evaluated. The effect of the radiation properties of the surface of solid lining layers on heat transfer is demonstrated.

Insulation co-ordination procedure for 420 kV gas insulated lines (GIL)
11th International Symposium on High-Voltage Engineering (ISH 99), 1999After stating the reasons leading to EDF's interest in 420 kV GIL and the technical and economic imperatives to be considered, the principles adopted for the insulation co-ordination of 420 kV GIL up to a few tens of kilometers long are described. All the insulation coordination approach is based on the global failure rate requested for GIL taking into

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

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.

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 ...
