  • Why the EU should ban gaz sf6 - Energy Post

    What Is sf 6? 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 gaz sf6 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 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.

  • Why SF₆ emissions from the renewable energy sector should not

    Increasing Sulfr hexafluorideGlobal Warming PotentialDecarbonisation FirstMeasurements show that SF₆ has been increasing in the atmosphere. While SF₆ emissions across Europe have more than halved since the mid-1990s, global emissions are increasing, mostly owing to increases in SF₆ emissions from the electrical industry, which are predicted to continue. Even so, it’s important to put the role of SF₆ as a greenhouse gas into context with other greenhouse gases. The most important sentence in the BBC’s article is this: Unfortunately, this critical point isn’t developed. The global concentration of atmospheric CO₂ today is about 410 parts per million, whereas the global concentration of SF₆ is only about 10 parts per trillion. In other words, there is 41 million times more CO₂ in the atmosphere than SF₆. But since SF₆ is 23,500 times stronger at trapping heat than CO₂, doesn’t this still mean it’s a bigger problem than CO₂ for the climate? CO₂ is actually a very weak greenhouse gas and is much less efficient at trapping heat compared to other greenhouse gase...

  • High voltage substations overview (part 1) | EEP

    Circuit ConfigurationProtective MeasuresArrangement and ModulesHigh voltage substationsare points in the power system where power can be pooled from generating sources, distributed and transformed, and delivered to the load points. Substations are interconnected with each other, so that the power system becomes a meshed network. This increases the reliability of the power supply system by providing alternate paths for flow of power to take care of any contingency, so that power delivery to the loads is maintained and the generators do not face any outage. The high voltage substation is critical component in the power system, and the reliability of the power system depends upon the substation. Therefore, the circuit configuration of the high voltage substation has to be selected carefully. Busbars are the part of the substation where all the power is concentrated from the incoming feeders, and distributed to the outgoing feeders. That means that the reliability of any high voltage substation depends on the reliability of the busbars present in t...
