Additional salt deposit density of polluted insulators in salt fog

The surface pollution layer of polluted insulator absorbs fog water and gets damp in salt fog. Meanwhile, the salts in the salt fog deposit on insulator surface, which increases the surface conductivity and degrades the flashover performance of insulators. At present, the effects of fog water conductivity (γ20) and equivalent salt deposit density (ESDD) are analysed separately, which does not reve...
