Why the European Union Should Ban Sulfr hexafluoride | Energy Central

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 sf6 gas Emissions Difficult? Do Better Solutions Exist?ConclusionSulfr hexafluoride 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 sf 6is 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

[Withdrawn] Managing fluorinated gases and ozone-depleting

IntroductionWho Is Affected?General GuidanceRefrigeration, Air Conditioning and Heat PumpsFire ProtectionMobile Air ConditioningHigh Voltage SwitchgearSpecialist SectorsEnforcementReportingFluorinated greenhouse gases (F-gases) are a group of chemicals containing fluorine. F-gasesare powerful greenhouse gases that trap heat in the atmosphere and contribute to global warming. Ozone-depleting substances (ODS) are gases which damage the ozone layer in the upper atmosphere. They are being phased out, but can be found in older equipment. There are also a few exceptions for certain uses. Common uses for ODS and F-gasesinclude refrigeration and air-conditioning equipment, aerosols, solvents, foam blowing agents, firefighting fluids and high voltage switchgear. This guide explains what F-gases and ODS are, how different types of businesses can comply with the F-gas and ODSlegislation, and how the legislation is enforced.Get price

Using Dissolved Gas Analysis to Detect Active Faults in Oil

Dissolved gas-in-oil AnalysisGases Detected and Their RelevanceExample 1Example 2Example 3Dissolved gas-in-oil analysis, performed in accordance with ASTM D3612 or IEC 60567, is by far the most frequently requested diagnostic test and the single most important test performed on transformer oil. As the insulating materials of an electrical apparatus, such as a transformer, break down from excessive thermal or electrical stress, gaseous byproducts form. The byproducts are characteristic of the type of incipient-fault condition, the materials involved and the severity of the condition. Indeed, it is the ability to detect such a variety of problems that makes this test such a powerful tool for detecting incipient-fault conditions and for root-cause investigations after failures have occurred. Dissolved gases are detectable in low concentrations (ppm level), which usually permit early intervention before failure of the electrical apparatus occurs, and allow for planned maintenance. The DGA technique involves extracting or stripping the gases from the oil and injecting them in...Get price
