Development of a Compressed-Gas-Insulated Transmission Line
IEEE Transactions on Power Apparatus and Systems, 1971Development of Compressed-Gas-Insulated transmission lines for voltages of 138 to 500 kV is described. Design, manufacture and installation are presented. Dielectric and mechanical tests data are given. A 230 kV single-phase outdoor test line of 230-ft length has been installed and voltage and current tests have been initiated.

Gas insulated transmission lines - GIL
2008 IEEE/PES Transmission and Distribution Conference and Exposition, 2004The 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. As a gas-insulated system, the GIL has the advantage of having electrical behavior similar to an overhead line. This is of importance to system operation.

Insulation co-ordination for gas-insulated transmission lines (GIL)
IEEE Transactions on Power Delivery, 2001For the transmission of high power over long distances underground the gas-insulated transmission lines (GIL) are a good technical solution as an alternative to an overhead line and in addition to cables. The GIL has two main advantages: low resistive losses because of large cross section of the conductor and enclosure and low capacitive load because ...

Corrosion protection for gas-insulated transmission lines
IEEE Power Engineering Society Summer Meeting,, 2003For buried gas insulated transmission lines (GILs), a coating against corrosion is absolutely necessary and similar to most other directly buried metallic installations. Active corrosion protection, also called catholic protection, may be added to take care about possible failures of the coating as an additional quality insurance system to the passive ...

Discussion of "Insulation coordination for gas-insulated transmission lines (GIL)" and closure
IEEE Transactions on Power Delivery, 2001A. Sabot comments on the paper by O. Volvker et al. (see ibid., vol.16, no.1, p.122-30, 2001). The author discusses three points: reference to the IEC standard 60071-2, the overvoltage calculations, and the GIL withstand voltage.

Heat Transfer Characteristics of Gas-Insulated Transmission Lines
IEEE Power Engineering Review, 1986This paper reports on an investigation of the heat transfer characteristics of GILs under constant temperatures and under changing temperatures influenced by solar radiation and wind. It was verified that values calculated by our heat transfer formulas coincided well with measured values both for current-induced temperature rise of the conductor and ...

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 ...

Underground links by gas insulated transmission lines
APSCOM 2000 - 5th International Conference on Advances in Power System Control, Operation and Management, 2000The concern to reduce the number of increasingly contested power transmission lines has led utilities and manufacturers as ALSTOM to search for new underground solutions. Today, the penetration of power lines into the heart of large cities is seriously hindered by the density of population and urban expansion.

Analysis on Common Faults of Gas Insulated Transmission Line
2020 4th International Conference on HVDC (HVDC), 2020Gas-insulated metal-enclosed transmission line (GIL) is a new type of transmission equipment, which can be used to connect overhead line, GIS, transformers and switchgear in power plants. With the development of UHV transmission projects in China, the amount of GIL projects is increasing year by year, while its faults have been paid more attentions by ...

Directly buried gas-insulated transmission lines (GIL)
PES T&D 2012, 2012Regarding the increasing interest in underground transmission systems, gas-insulated lines (GIL) represent an attractive alternative to cable solutions. Changes in the regulatory framework with respect to planned extensions of extra high voltage (EHV) systems have intensified the demand for underground transmission lines in general.
