⁃ Intrinsic (material-controlled) versus extrinsic (environment-controlled) dielectric breakdown of parts, showing:

        ⁃ How the damage pattern depends on the type of breakdown  

        ⁃ Why the dielectric breakdown strength [in kV/mm] decreases with molded part thickness

        ⁃ Why the breakdown strength is higher in DC than in AC

⁃ Data and observations on electro-ageing.
