Climate change: Electrical industry'dirty secret' boosts

Scientists say this is not all coming from countries like India, China and South Korea. One study found that the methods used to calculate emissions in richer countries "severely under-reported" emissions over the past two decades. Why hasn't this been banned? Sulfr hexafluoride comes under a group of human-produced substances known as F-gases.

History of Atmospheric gaz sf6 – Matt RigbyHomepage

Jan 16, 2011 · Sulfur hexafluoride (gaz sf6) is a particularly potent greenhouse gas. It is used in large electrical equipment, and leaks into the atmosphere during maintenance. Once it is in the atmosphere, it is only destroyed if it reaches very high altitudes, making it last for hundreds to thousands of years.

Next Generation Dry-air GIS - Solar Impulse Efficient Solution

Dry-air medium voltage gas insulated switchgear replaces sf 6 with dry air. This GIS uses pressurized dry air instead of sf6 gas as its insulating medium. Its design builds on all the advantages of traditional sf6 gas-based GIS systems but operates with simple atmospheric air and is therefore much easier and cost-effective to manufacture and operate.

Why the EU should ban sf6 gas

What Is Sulfr hexafluoride? and How Is It used?Is sf 6 A Danger to Human Health?How Environmentally Damaging Is It?Has The Environmental Impact Even Been Underestimated?Is The Mitigation of Sulfr hexafluoride Emissions Difficult? Do Better Solutions Exist?Conclusionsf 6 is a long-lived, highly potent greenhouse gas. It is manmade and combines excellent electrical properties with chemical stability and low toxicity. Moreover, It’s non-flammable and low in cost. These characteristics have led to its widespread and enthusiastic adoption by the electrical industry, which uses approximately 80% of all sf6 gasproduced (Powell, 2002: 6). Within the electrical industry sf6 gasis used as an insulating medium for medium (MV) and high (HV) voltage electrical switchgear. A switchgear is the combination of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate sections of electrical grids. Low-voltage (LV) switchgear are used for controlling electrical circuits within buildings, medium voltage (MV) switchgear for controlling the electrical grids within cities and towns, and high voltage (HV) switchgear for grids that span a greater geographical area such as countries and regions.
