With an equal flow in M1, M2 and M3 we expected an higher concentration of CF4 because we increase flow in M1 which is the less efficient membrane but CF4 percentage decrease. This probably because we didn

    Feb 01, 2018With the aim to prevent any fault or failure of a transformer, the authors in have analyzed data collected from the tripping caused by transformers and protective relays. The analysis have shown that 87% of the transformer’s tripping occurs, due to the power system faults followed by 10% of false operation of protective relays, and the rest is due to the failures within the transformer itself.Cited by: 77

  • Myth About SF6 Gas In Electrical Equipment

    May 25, 20203. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. However in electrical switchgear the SF6 gas is always used in gas-tight compartments, greatly minimising leakage.
