Management of gas-insulated transmission lines magnetic fields

11th International Symposium on High-Voltage Engineering (ISH 99), 1999
Recent 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 ...

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), 2018
An 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 ...

220 kV gas-insulated transmission line-Palexpo Geneva Switzerland

2003 IEEE Power Engineering Society General Meeting (IEEE Cat. No.03CH37491), 2004
This paper describes the first application in Geneva of the second generation GIL developed using N/sub 2//SF/sub 6/ gas mixtures. An existing high-voltage overhead transmission line had to be replaced because of the extension of buildings for the Palexpo fairs. The existing 220 kV line had to be laid underground for a length of about 420 m, mainly due

Optimized Design of Active Particle Traps for Gas Insulated Transmission Line

2024 7th International Conference on Energy, Electrical and Power Engineering (CEEPE)
Metal particles moving in gas-insulated metal-enclosed transmission lines (GIL) are an important factor that induces equipment insulation failures, Particle traps are an important measure to inhibit the movement of metal particles, and the optimization ...
