With a GWP value (Global Warming Potential) or CO 2 e (CO 2 equivalent) of 22,800, SF 6 is the most climate damaging gas of all known greenhouse gases. 1 kg of SF 6 in the atmosphere contributes to the greenhouse effect to the same extent as 22,800 kg carbon dioxide (CO 2 ). The residence time in the atmosphere is 3,200 years.

sf6 switchgear Purity equation working principle

Physics of Conduction in SolidsUsesInsulation in Electrical ApparatusTelegraph and Power Transmission InsulatorsInsulation of AntennasSee AlsoReferencesElectrical insulation is the absence of electrical conduction. Electronic band theory (a branch of physics) dictates that a charge flows if states are available into which electrons can be excited. This allows electrons to gain energy and thereby move through a conductor such as a metal. If no such states are available, the material is an insulator. Most (though not all, see Mott insulator) insulators have a large band gap. This occurs …See more on en.wikipedia.orgPhysics of conduction in solidsUsesInsulation in electrical apparatusSwitchgear Wikipedia en.wikipedia.org/wiki/SwitchgearComponentsFunctionsHistoryHousingCircuit Breaker TypesProtective CircuitryClassificationSafetySee AlsoA switchgear assembly has two types of components: 1. Power conducting components, such as switches, circuit breakers, fuses, and lightning arrestors, that conduct or interrupt the flow of electrical power. 2. Control systemssuch as control panels, current transformers, potential transformers, protective relays, and associated circuitry, that monitor, control, and protect the power conducting components.See more on en.wikipedia.orgComponentsFunctionsHistoryHousingCircuit breaker typesClimate change: Electrical industry's 'dirty secret' boosts warming … bbc/news/science environment 495671972019/9/13Climate change: Electrical industry's 'dirty secret' boosts warming.
