Popis: Almost all the MV and HV switchgears used by power utilities for interrupting faults are Sulphur Hexaflouride SF6 gas circuit breakers as this gas has the best dielectric properties to quench the onset of an arc in the event of fault. However due to strong dissociating properties of this gas when in contact with air that can release fluorine into the atmosphere, the Kyoto protocol has mandated to reduce the usage of SF6 in the future. SF6 is a greenhouse gas and it’s about 3000 more severe than CO2. And that’s the reason for replacing this gas. A close match in the quenching properties to SF6 that is now being intensively researched is nitrogen N2. This gas is considered to be an inert gas, and its release into the atmosphere has no harmful effects (except for asphyxiation – which can be easily handled with awareness). As the need for a replacement of SF6 becomes critical in the near future, the urgency to find the right gas is immediate. Hence the proposed work in this paper is to make a comprehensive pa...
