  • Correlation for the Viscosity of Sulfur Hexafluoride (SF6

    Apr 25, 2012 · A wide-ranging correlation for the viscosity surface of sulfur hexafluoride (SF6) has been developed that incorporates generalized friction theory (GFT). The approach requires, as the core thermodynamic model, a reference quality nist-equation of state (EoS). Here the EoS of Guder and W. Wagner has been selected for that purpose.

    Dec 01, 1988 · The integrated IR intensities of the v3 and v4 bands of SF6 were measured by Kim et al. (44) using the Wilson-Wells-Penner-Weber method. Integrated IR intensities of SF6 in the v3 and v4 region were also measured by Brodbeck et al. (45). Up to a density of about 0.25 amagat, there was a linear dependence of the integrated absorption with density.

Many of the methods described in this article can be performed as an acceptance or maintenance test, depending on conditions such as the test voltageapplied or duration of test. The objective of any diagnostic test is to identify problems that may exist with a cable - in a non-destructive way - so that preventative measures can be taken to avoid potential failureof that cable when in service. Diagnostic assessments may apply to cable systems comprising of the cable itself and the associated accessories such as splices and terminations.
