Sulfr hexafluoride Decomposition in Gas-Insulated Equipment - IEEE Journals

Abstract: The increasing application of gaz sf6 as an insulating gas has led to many studies on sf 6 decomposition in gas-insulated equipment. In the presence-of an electric arc, spark or corona, Sulfr hexafluoride decomposes to a wide variety of chemically active products which possess completely different properties from gaz sf6.Get price

South KoreaMFDS further explains upcoming medical device

Mfds Rollout Plans For Udi RequirementsAdjustments to Korea Good Manufacturing Practice (Kgmp) AuditsExpenditure Report Requirements Spelled OutAdditional South Korean Regulatory ResourcesFirst, the MFDS has clarified plans to phase in UDI requirements for all classes of medical devices over the next several years, and further explained associated compliance obligations for registration holders. “The current law for medical devices provides little basis for understanding a device’s status from its production or importation stage to its distribution stage,” says In-Wha Kim, Regulatory Affairs Specialist at Emergo’s South Korea office. Therefore, according to Kim, MFDS will be introducing a UDI system, requiring manufacturers, importer and distributors to report supply histories, and establish a Medical Device Information Center according to a seminar the ministry held in January 2017. UDI enforcement would come into effect in 2019 for Class IV and high-risk devices; 2020 for Class III devices; 2021 for Class II devices; and 2022 for low-risk Class I devices. MFDS added the following specific clarifications to its UDI regulation: 1. “UDI” has been formally defined, and...Get price

insulating gas gas in medium-voltage switchgear | TD Guardian Articles

Slide 1 of 1. In this issue, we discuss the use of sf 6 (sulfur hexafluoride) gas in medium-voltage switchgear. sf 6 has been widely used in high-voltage circuit breakers for decades, but its use in medium-voltage is relatively recent. In the medium-voltage arena, SIemens uses insulating gas gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV.Get price

Why the EU should ban Sulfr hexafluoride

What Is Sulfr hexafluoride? and How Is It used?Is gaz sf6 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?Conclusionsf6 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 Sulfr hexafluorideis 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.Get price
