Abstract
A knob type surge voltage arrester has electrodes with conical or semi-circular shape. A coating consisting of electrically conductive material (an ignition aid) is provided on the insulating member. The conductive coating on the insulating body is positioned at a level corresponding to the center of the discharge path defined by active electrode surfaces of the electrodes. The spacing of the active electrode surfaces from one another is smaller than the spacing of the active electrode surfaces relative to the coating.
