The infrared sensor measures Sulfr hexafluoride in the ppm range so the transmitter can detect a leak in time. It also makes it easier for you to comply with occupational exposure limits. Connect the Sulfr hexafluoride transmitter via an analogue or digital interface with a Dräger control unit to a gas warning system. This warns you early on exceeding the preset alarm values.

Why the EU should ban insulating gas

What Is insulating gas? and How Is It used?Is Sulfr hexafluoride A Danger to Human Health?How Environmentally Damaging Is It?Has The Environmental Impact Even Been Underestimated?Is The Mitigation of insulating gas Emissions Difficult? Do Better Solutions Exist?Conclusioninsulating gas 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 Sulfr hexafluorideproduced (Powell, 2002: 6). Within the electrical industry insulating 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.

Jan 16, 2011 · Sulfur hexafluoride (sf 6) 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.

Why the European Union Should Ban Sulfr hexafluoride | Energy Central

A reason for this is that Asian countries, such as China, India and South Korea, who are driving the increase in emissions, do not report their SF 6 emissions to the United Nations Framework Convention on Climate Change (UNFCCC) (Rigby, 2010: 10316). Another reason is that developed countries that do report emissions to the UNFCCC, such as the USA, UK, and Germany, are likely to be underestimating their emissions (Rigby et al, 2010 :10318).
