The aim of this study was to evaluate the sulphur hexafluoride (SF6) tracer technique for methane (CH4) emission measurement in sheep. Ten cryptorchid Romney sheep were involved in two indoor trials (T1 and T2), where daily CH4 emissions were individually measured both by the SF6 tracer ('tracer CH4') and by the indirect calorimetry chamber ('chamber CH4') techniques while fed on lucerne hay at...

Hydrogen sulfide (H2S) and sulfur dioxide (SO2) are two typical decomposition byproducts of hexafluoride (SF6), commonly used as an insulating medium in electrical equipment; for instance, gas circuit breakers insulated switchgears. In our work, fiber-like p-CuO/n-ZnO heterojunction sensing materials were successfully prepared via the electrospinning method to detect SF6 byproducts, H2S SO2 gas...

Abstract: The application of electric field theory to widely different aspects of electrical insulation has led to more understanding the phenomena. Electric fields may be considered as the main reason for insulation failure. The purpose of this paper is to modify importance of analyzing electric field in insulation design. The SF6 circuit breaker is chosen as case study that encounters cri...
