Real-time gas insulation state evaluation model of the gas insulated switchgear
2017 13th International Conference on Natural Computation, Fuzzy Systems and Knowledge Discovery (ICNC-FSKD), 2017Gas insulated switchgear (GIS) has been applied greatly in the ultra-high voltage (UHV) power grids because of its advantages of high reliability, compact structure, small footprint, low electromagnetic pollution and so on. Therefore, the real-time monitoring of its operation status is important for ensuring the reliable and safe operation of the power

Transient heating of gas insulated switchgears
IEEE PES T&D 2010, 2010This 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.

Coupling Devices for the Detection of Partial Discharges in Gas-insulated Switchgear
IEEE Power Engineering Review, 1981Partial discharge in gas-insulated 8witchgear is indicative of serious malfunction and, otten, imminent failure. Partial discharge magnitudes range from zero to about a microcoulomb per pulse. Sources of partial discharge can be detected acoustically, electromagnetically or through gas analysis.
