Typical Internal Defects of Gas-Insulated Switchgear and

Dec 04, 2017 · Gas-insulated switchgear (GIS) is a common electrical equipment, which uses sulfur hexafluoride (insulating gas) as insulating medium instead of traditional air. It has good reliability and flexibility. However, GIS may have internal defects and partial discharge (PD) is then induced. PD will cause great harm to GIS and power system. Therefore, it is of great importance to study the intrinsic

The tubes are pressurised with a N2/gaz sf6 gas to provide the main insulation. The main advantage of GIL is that a higher cable rating can be achieved than with solid insulation cables and the terminations at the cable ends are less complex and less prone to failure. Fig. 1 shows a GIL system in the process of installation.
