Epoxy insulator with surface graded-permittivity by magnetron sputtering for gas-insulated line
IEEE Transactions on Dielectrics and Electrical Insulation, 2020To reduce the electric field concentration induced flashover in AC gas insulated line (GIL), a novel concept of surface functionally graded material (SFGM) is proposed in this paper, and the continuously graded high-A layer was fabricated by depositing BaTiO 3 on the insulator surface.

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.

Compressed-gas insulation for concentric power lines
1968 8th Electrical Insulation Conference, 1968This paper will describe two methods of significantly improving the reliable insulating ability of concentric-gap gas-filled systems. The first of these makes use of a thin dielectric coating bonded on one or both concentric conductors. The second utilizes the field of the concentric line to remove free conducting particles electrostatically from the ...

Electric field analysis of insulating spacers for a superconducting gas-insulated transmission line
2018 12th International Conference on the Properties and Applications of Dielectric Materials (ICPADM), 2018An essential component of the new superconducting power cable concept called Superconducting Gas Insulated Line (S-GIL) is the insulating spacer that ensures the position in the center axis of the cylindrical, grounded cryostat. The material choices and the design topologies for the insulating spacers are presented for both the rigid and flexible ...

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.

Solution of coupled electromagnetic and thermal problems in gas-insulated transmission lines
IEEE Transactions on Magnetics, 2003Gas-insulated high-voltage and extra high-voltage transmission lines are a new technology for transmitting high-power ratings over long distances. A previous paper was devoted to predict the current distribution along with the external flux density in this multiconductor system, highlighting its proximity effect.

Multiphysics Modeling for Transient Analysis of Gas-Insulated Lines
IEEE Transactions on Power Delivery, 2018In this paper, two discretization techniques are combined to present a coupled electro-thermal model for the transient analysis of gas-insulated transmission lines (GILs). The analysis of the thermal problem is based on the volume-element-method, representing heat transfer equations on a 2-D axisymmetric GIL model and determining temperature ...

Thermal and magnetic analyses of gas-insulated lines
Electric Power Systems Research, 2009Abstract This paper presents the factors affecting current rating “ampacity” of buried three-phase, naturally cooled isolated-phase gas-insulated lines (GIL) with flat formation and finite-element simulation of double-circuit, three-phase GIL inside a tunnel to calculate the magnetic-flux and current densities.

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 ...

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.
