Health and environmental dangers of sf 6-filled switchgear

SF 6 is a greenhouse gas In1997, SF 6 was identified by the Intergovernmental Panel on Climate Change (IPCC) as a highly potent greenhouse gas which contributes to climate change. SF 6 is 22 000 times more effective at trapping infrared radiation than an equivalent amount of carbon dioxide over a 100-year period [21].Get price

Regulation of Air Pollution: South Africa

I. IntroductionII. National Environmental Management: Air Quality ActIII. Fuel Emission StandardsIV. Carbon Tax BillSouth Africa’s GHG emissions are among the highest in the world and its absolute carbon dioxide (CO2) emissions rank among the top twenty countries, “with emissions per capita in the region of 10 metric tons per annum.”The 2011 National Climate Change White Paper described this challenge as follows: South Africa has national and international legal obligation to reduce its emissions. The Bill of Rights section of the South African Constitution includes an environment clause, which states that South Africa is party to a number of multinational environmental agreements. These include the United Nations Framework Convention on Climate Change (UNFCCC), which South Africa ratified in 1997; the Kyoto Protocol, which South Africa ratified in 2002; and the Paris Agreement on Climate Change, ratified by South Africa in 2016.In the 2009 Copenhagen Climate Change Conference, South Africa committed to reducing its GHG emissions by 34% below its current levels (see below) by 2020 and 42% below c...Get price

An alternative to sf6 gas in electrical switchgear - EE Publishers

For decades, the unique properties of sulfur hexafluoride (Sulfr hexafluoride) have made it popular as an insulation and switching medium for electrical switchgear. However, Sulfr hexafluoride is a greenhouse gas and there are life-cycle management costs associated with its use. For some years, ABB has been conducting research into alternatives with lower environmental impact but with […]Get price

Opening of 132kV Breaker with Very Low Sulfr hexafluoride Pressure - CR4

Opening a completely isolated sf6 gas breaker with very little or no Sulfr hexafluoride gas (as if it were in a testing lab) would pose no threat to the health of the breaker. There is no auto-trip feature. I think auto-trip at such low gas pressure may not be desirable because arcing might start across the open contacts of breaker due to very less insulationGet price

Intravitreal tPA Injection and Pneumatic Displacement for

AbstractIntroductionCase PresentationDiscussionConsentAuthors’ ContributionsAcknowledgmentsBackground. Submacular hemorrhage can occur after blunt trauma to the eye. Intravitreal tissue plasminogen activator (tPA) and gas injection are often used for treatment and are effective for submacular hemorrhage caused by age-related macular degeneration. This report describes the clinical outcome in a child with submacular hemorrhage caused by traumatic choroidal rupture who underwent successful intravitreal tPA injection and pneumatic displacement.Case Presentation. A 10-year-old boy developed sudden decrease of vision and a central scotoma in his right eye after trauma. Submacular hemorrhage was found in the eye. Visual acuity was 20/70 OD. Tissue plasminogen activator (12.5 μg in 0.05 mL) and 0.3 mL of pure sulfur hexafluoride were injected into the vitreous cavity under general anesthesia. After surgery, the patient was instructed to maintain a prone position. Displacement of the submacular hemorrhage from the fovea revealed a choroidal rupture, presumed to be the cause of th...Get price
