Abstract: A surge arrester has a tube-shaped housing, an end fitting connected to an end of the housing, a varistor block arranged in the housing and a supporting element arranged in the region of the end fitting. The supporting element has a supporting ring which is in contact with the housing and which includes a cone and a clamping ring with a counter-cone that corresponds to the cone. The cone is braced to the counter-cone in such a manner that the supporting ring is pressed to the housing in a non-displaceable manner. The supporting element can thus also be used after the installation of the varistor block and also be removed.

Abstract: A discharge element includes a first electrode that is made of a plastically-deformable conductive material and that has an internal space and an opening communicating with the internal space, a base that is made of an insulating material and that is air-tightly joined to the opening so that the internal space of the first electrode becomes an airtight space, and a second electrode that is made of a conductive material and that is inserted into the internal space via the base so as to form a spark gap between itself and the first electrode. Therefore, it is possible to provide the discharge element that realizes a high production yield, a simple structure, and a cost reduction and a simple manufacturing method of the discharge element.

Abstract: The present invention provides a glow discharge cell comprising an electrically conductive cylindrical vessel having a first end and a second end, and at least one inlet and one outlet; a hollow electrode aligned with a longitudinal axis of the cylindrical vessel and extending at least from the first end to the second end of the cylindrical vessel, wherein the hollow electrode has an inlet and an outlet; a first insulator that seals the first end of the cylindrical vessel around the hollow electrode and maintains a substantially equidistant gap between the cylindrical vessel and the hollow electrode; a second insulator that seals the second end of the cylindrical vessel around the hollow electrode and maintains the substantially equidistant gap between the cylindrical vessel and the hollow electrode; a non-conductive granular material disposed within the gap, wherein the non-conductive granular material (a) allows an electrically conductive fluid to flow between the cylindrical vessel and the hollow electrode

Abstract: The present invention generally relates to a low temperature plasma probe for desorbing and ionizing at least one analyte in a sample material and methods of use thereof. In one embodiment, the invention generally relates to a low temperature plasma probe including: a housing having a discharge gas inlet port, a probe tip, two electrodes, and a dielectric barrier, in which the two electrodes are separated by the dielectric barrier, in which application of voltage from a power supply generates a low temperature plasma, and in which the low temperature plasma is propelled out of the discharge region by the electric field and/or the discharge gas flow.

Abstract: A spark gap includes two terminal electrodes enveloping a cavity. The cavity includes an electrical discharge space between the two terminal electrodes. The spark gap also includes an electrical insulator between the two terminal electrodes.

Abstract: An overvoltage protection device (1) with a first electrode (2) which has a first arcing horn (3), with a second electrode (4) which has a second arcing horn (5), with an air-breakdown spark gap (6) which is active between the arcing horns (3, 5), and with a housing (7) which accommodates the electrodes (2, 4), has the two arcing horns (3, 5) shaped and arranged relative to one another such that they diverge from a lower ignition area (8) to their outer ends (9, 10), so that the air-breakdown spark gap (6) widens outwardly, proceeding from the ignition area (8). The overvoltage protection device (1) has a current carrying capacity which is as high as possible and a high network follow current extinction capacity with an overall height which is as small as possible by the first arcing horn (3) being made in the shape of a truncated cone and the second arcing horn (5) being located concentrically around the first arcing horn (3).
