Modeling of the Electric Field in High Voltage Direct Current Gas Insulated Transmission Lines
IEEE International Conference on Dielectrics, 2022High voltage direct current (HVDC) gas insulated systems are utilized when space is limited. The composite of SF6 gas insulation and solid spacer insulation results in high electric field values in the vicinity of the sheath under DC conditions.

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 ...

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 ...
