Abstract: There is disclosed a method of diffusing gaseous medium such as tritium into a vessel such as a tube of an overvoltage protector. According to the method, a vessel such as a tube including a wall portion made of a material permitting diffusion of gas therethrough is provided. This vessel is heated to a predetermined elevated temperature and sealed while the vessel is at the elevated temperature. The vessel is thereupon evacuated and exposed to an atmosphere of gas to be diffused into the vessel while maintaining this atmosphere for a predetermined period of time at an elevated temperature less than the sealing temperature and at a pressure higher than the pressure within the sealed and evacuated vessel, thereby causing diffusion of gas into the vessel for filling the same with the gas. There is also disclosed a device for carrying out the hereinbefore described method.

Abstract: A network communication device and printed circuit board are provided with transient energy protection. The network communication device includes a transceiver, a transformer, a connector, a spark gap, and a transient energy trigger circuit. The transformer is coupled between the transceiver and the connector. The spark gap and the transient energy trigger circuit are coupled in parallel, between the transformer and a ground end. Alternatively, the spark gap and the transient energy trigger circuit are coupled in parallel, between any two of differential signal lines of the transformer. The spark gap and the transient energy trigger circuit provide a multi-path structure for conducting away the transient energy. A first transient energy is conducted to the ground end through the transient energy trigger circuit, while a second transient energy is conducted to the ground end through the spark gap.

Abstract: A lightning arrester for discharging electricity from an electrode in a container of the ground voltage level filled with electric insulation fluid when an excessive voltage is imposed on the electrode. The arrester has characteristic elements for selectively discharging electricity and an insulation tube for enclosing the characteristic elements. The insulation tube is so arranged as that part of the characteristic elements are inserted in the container and some of them project out. The characteristic elements are connected to the electrode in the container, and selectively connected and disconnected to the ground.

Abstract: An electrode configuration for an electrical component, in particular a surge protector, includes two electrodes extending in a plate-shaped manner parallel to a radial plane relative to a connection axis of the electrodes, defining an axial direction. At least one electrode has a connection region lying in the radial plane and at least two, three or four ribbon-shaped strips each extending away from the connection region and at least partially in circumferential direction relative to the axial direction. A fault arc, occurring during a lightning strike, can be conducted outwards away from the electrical component and forced into rotation around the electrical component in an effective manner due to the ribbon-shaped strips at the outer edge of the connection region and at least two ribbon-shaped strips overlapping each other at a spacing with respect to their delimiting surfaces lying perpendicular to the axial direction.

Abstract: A triggered vacuum gap (TVG) device that has application as a closing switch for synchronized closing in distribution and transmission power systems. The TVG device controllably sustains a current arc in the device through initial current zeros created by power system transients and, thereby, prevents premature interruption of the closing operation. The TVG device includes main electrodes defining a vacuum gap therebetween and a triggering electrode providing a triggering gap between one main electrode and the triggering electrode. The TVG device also includes a triggering circuit having a high voltage impulse source that supplies a fast rising impulse voltage to the one main electrode and the triggering electrode for creation of a plasma to provide an initial breakdown of the triggering gap and a low voltage unidirectional current source that supplies current to the one main electrode and the triggering electrode once the first triggering gap breakdown has occurred.
