Abstract:
The accident rate of gas-insulated switchgears (GIS) is considered. The statistical sample covered 30 110-500 kV switchgear switchgears in a vast region of the European part of the country for the period 2008-2022. Their design features and technical characteristics are given. Significant and insignificant failures of GIS, including their structure, namely, distribution by elements of installations, technical and organizational causes of occurrence, dependence on the year of operation are subjected to analysis. The flow parameter (frequency) of GIS failures is determined, as well as the maximu

Abstract:
Abstract The current medium voltage Gas Insulated Switchgears (GIS) predominantly use Sulphur Hexafluoride (SF6) as insulation medium. The leakage tests performed on GIS use either SF6 or Helium medium to ensure gas tightness. However, SF6 has been strictly regulated for the last years due to the high global warming potential effect on the planet. As a response, new technologies are emerging using air as insulation medium. The present work establishes a basic comparison of the leakage rate in a medium voltage GIS using two different leak detection methods: Helium leak detector and Residual Gas

Abstract:
Gas-insulated switchgear malfunctions during power system operation may occur due to electrical, thermal, or human errors in the manufacturing process. The leading causes of insulation deterioration of gas-insulated switchgear are discharging along the surface caused by dirt on the insulating material, internal discharge caused by impurities and cavities in the insulating material, corona discharge caused by poor assembly or construction at the site, and electric tree channel discharge caused by the intense internal discharge. Since different defects produce different partial discharge charact

Abstract:
Sulphur hexafluoride (SF6) gas and SF6 gas mixtures are widely used in gas-insulated systems (GIS) because they have good dielectric and thermal properties. Among the various gas mixtures investigated so far, SF6-air, SF6-CO2, and SF6-N2 are most used gas mixtures. Also, these mixtures have much technical superiority in GIS. These are nontoxic and nonflammable gases, and they have less sensitivity to nonuniformities and higher liquefaction temperature at high pressure. GIS, switchgears, circuit breakers, and substations are systems that work with alternating current and have nonuniform electri
