Gas-Insulated Switchgear and Interrupter

IEEE Transactions on Electrical Insulation, 1986
The historical progress of gas-insulated equipment in Japan is reviewed and the trend of technologies is discussed in the present paper. Since gas-insulated switchgear (GIS) and gas circuit breaker (GCB) have been widely applied to substation equipment, advanced technologies for high realiability and compactness of GIS are still required.

Transient heating of gas insulated switchgears

IEEE PES T&D 2010, 2010
This paper investigates the thermal effects of short fault currents in switchgears. During short circuits, the current and temperature distribution over the cross section and even along the perimeter of the busbars and the enclosures can become non-uniform, exposing the separate contact elements of the contact systems to different temperatures.

Testing Methods for Gas-Insulated Switchgear

IEEE Transactions on Electrical Insulation, 1986
This paper presents the outline and basic concepts of insulation tests which have been contributing to GIS's steady progress in Japan. Some examples of insulation tests during developing, production, and installation stages are described. Finally, the current trends of GIS's insulation tests are described.

Sustainable performance of Gas-Insulated Switchgear

2012 International Conference on High Voltage Engineering and Application, 2012
Modern Gas Insulated Switchgear (GIS) technology has been undergoing continual development since its introduction in the 1960's when the use of SF6 as arc extinguishing and isolating medium was first introduced, and whilst many may consider this technology as mature, there have been continuous development driven changes in GIS design, manufacture, test
