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, sf6 gas 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 sf6 gas gas can be used in several medium voltage gas insulated switchgear systems. However, for such devices, gaz sf6 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
