There has been a considerable progress in understanding the physics and technology of high power pseudospark switches, which allows their implementation in pulsed power applications. These switches have very wide dynamic range of breakdown voltage operation: from 1% to 99%. Single-gap systems still have the disadvantage of small hold-off voltage, which is(More)
Sulphur hexafluoride (SF<inf>6</inf>) is the most common insulation gas in high voltage technology. Besides the excellent insulation properties SF<inf>6</inf> has the most known global warming potential with a long lifetime in the atmosphere. Alternative insulation gases have only a fraction of the insulation level of SF<inf>6</inf>. The electric strength(More)

The electric Field distribution inside a bushing is given by capacitive and resistive components of the insulation materials. Capacitive components can be controlled by conductive foils which form a grading. In this case, the layers of a bushing core represent metal-insulator arrangements. The DC field distribution is dominated by the resistive components.(More)
