SF6 Density OverviewMonitoring SF6 Density with Gas Density IndicatorsGdi 100 D For Extreme Accuracy and Ease of UseSulfur hexafluoride (SF6) 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 SF6inside the equipment must re…See more on blog.wika.usEstimated Reading Time: 4 minsPeople also askHow does a SF6 gas density monitor work?How does a SF6 gas density monitor work?Small SF6 gas density monitor that automatically compensates for gas pressure changes due to ambient [...] Large gas SF6 monitor providing mechanical and local indication.

Insulated gas alarm quality check guide

2017/8/24Pure SF6 is physiologically completely harmless for humans and animals. It's even used in medical diagnostic. Due to its weight it might displace the oxygen in the air, if large quantities are concentrating in deeper and non ventilated places. Legislation for chemicals does not categorise SF6 as a hazardous material.

2013/11/28SF 6 gas pressure for insulating purpose is generally kept below 2.5 bar whereas SF 6 gas pressure for interrupting purpose is ranged from 5 bar to 7 bar. As vacuum technology is not available for high voltage, so for GIS or gas insulated switchgear system above 72.5 KV, only SF 6 is used both for interruption medium and insulation.
