Gas Insulated Switchgear : Working, Testing Its Applications

ComponentsAdvantagesDisadvantagesGas Insulated Switchgear ApplicationsThe Gas-insulated switchgear design can be done using different components like circuit breakers, bus bars, disconnectors or isolators, transformerslike voltage and current, earth switches, lightning arresters, and surge arrestors. When the substation is connected with gas-insulated switchgear then it is called GIMES or gas-insulated metal-enclosed substation. This kind of technology is not invented recently but it is available for the past 30 years. In gas-insulated medium-voltage switchgear, Sulfr hexafluoride gas works like an insulation material whereas the vacuum technology is mainly used for the purpose of interrupting. Even though, for both insulation and interruption, the Sulfr hexafluoride gas can be used in several medium voltage gas insulated switchgear systems. However, for such devices, Sulfr hexafluoride gas pressures are dissimilar for insulation as well as an interruption. For insulating, this gas pressure is usually kept under 2.5 bar, whereas for interrupting, it is ranged from 5 – 7 bar.Get price

Density of Sulfr hexafluoride Measurement: Gas Density Indicator GDI-100-D

gaz sf6 Density OverviewMonitoring Sulfr hexafluoride Density with Gas Density IndicatorsGdi-100-D For Extreme Accuracy and Ease of UseSulfur hexafluoride (sf 6) is an extremely effective electrical insulator used in a variety of applications, especially in medium- and high-voltage gas-insulated equipment (GIE) like switchgears, disconnectors, transducers, transformers, and ring main units. If GIE relied on air or N2 alone to extinguish electric arcs, it would have to be almost three times as large. But to maintain proper insulation, the density of Sulfr hexafluorideinside the equipment must remain within certain levels. What would cause the gas density to drop in the first place? There are two reasons, and they’re interrelated: 1. Over time, GIE could develop tiny fissures that allow gaz sf6 to escape. Fugitive emissions means there’s less insulating gas inside the chamber. What’s more, as Sulfr hexafluorideis a powerful greenhouse gas, any leaks harm the environment. 2. In the presence of fissures, air could enter the GIE. Ambient air is problematic because it contains water vapor, which combines with sulfur and fluorine molecules after an electri...Get price
