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 ...

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.

2020 IEEE International Conference on Advances and Developments in Electrical and Electronics Engineering (ICADEE), 2020
In an Electrical power system, the generating plants are located far away from the loads and gets transmitted through transmission lines. The transmission line can be an overhead line or underground cable. For the last forty-five years, a new technology GITL has been presented as a substitute for underground cables.

Insulation Design of Superconducting Gas Insulated Transmission Line
2020To improve the insulation performance of superconducting gas insulated transmission line (S-GIL), this chapter puts forward the two E-field regulating methods: E-field adaptive insulator and surface functional graded material (SFGM) insulator. The two simulation models of insulator in S-GIL are completed for optimize the E-field distribution of ...

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.

Handbook for Gas Insulated Substations and Transmission Lines
2012 IEEE Power and Energy Society General Meeting, 2012The Handbook for Gas Insulated Substations (GIS) and Transmission Lines (GIL) will be discussed in a panel session at the General Meeting (GM) of PES in San Diego in July 2012. The original idea for a handbook on GIS and GIL came out of the experiences made with the IEEE tutorials on the same subject which were given more than 20 times around U.S ...

Basic properties of hybrid gas‐insulated transmission lines (H‐GIL)
Electrical Engineering in Japan, 1997The recent trend in electric power consumption shows a steady increase and concentration in large cities and industrial districts. This indicates a strong need for a long-distance and enclosed-type power transmission line with large capacity and high reliability.
