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.

Reliability of Gas Insulated Substations and Switchgears with Traditional Insulation

Power Technology and Engineering, 2003
A comparative analysis of the parameters of reliability of switchgears with SF6 and conventional insulation is performed. It is shown that the use of gas-insulated switchgears is preferable for the conditions of the power system of Russia. Ways of renovating switchgear equipment in the networks of power systems are outlined.
