Dielectric barriers under lightning impulse stress: Breakdown and discharge-dielectric interaction in short non-uniform air gaps [PDF]
, 2019 Dielectric-air insulation systems can reduce the carbon footprint of medium voltage switchgear, as they can replace SF6-insulated systems. Such replacement is, however, not easy, as the devices are typically compact and complex, with strongly ...
