Abstract
A high voltage shielding device including a main body having an enclosing outer solid insulating wall, an outer electrode arranged on the solid insulating wall providing a first level of insulation to the outer electrode, and a first inner electrode which is uninsulated or has a coating providing a second level of insulation, which second level of insulation is lower than the first level of insulation. The first inner electrode is oriented relative the outer electrode in such a way that the first inner electrode mainly shields a component of an electric field which is perpendicular to a component of an electric field mainly shielded by the outer electrode.
