| Zusammenfassung: | A portable gas analyzer is provided for detecting SF6 decomposition products in electrical equipment to signal a warning before decomposition reaches the stage that the presence of the decomposition products causes degradation of the solid insulating materials used in the construction of the SF6 equipment. The forewarning of the decomposition products anticipates costly breakdowns. The portable gas analyzer is based on the principle of non-destructive testing wherein the surface sensitivity of selected insulating materials which decrease rapidly when exposed to increasing concentrations of SF6 decomposition products is measured. |
