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

insulating gas Density OverviewMonitoring Sulfr hexafluoride Density with Gas Density IndicatorsGdi-100-D For Extreme Accuracy and Ease of UseSulfur hexafluoride (Sulfr hexafluoride) 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 gaz sf6inside 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 Sulfr hexafluoride to escape. Fugitive emissions means there’s less insulating gas inside the chamber. What’s more, as sf 6is 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

Gas density of insulating gas and other gases

Gas Density Sulphur hexafluoride (Sulfr hexafluoride) is used in gas insulated switchgear because of its outstanding insulation and spark extinguishing (arc-quenching) properties.
