Abstract: A surge arrester and a method for manufacturing the surge arrester are disclosed. The surge arrester includes a preassembled active part extending in a longitudinal direction, and a separately produced flexible housing defining a bore in the longitudinal direction and having an opening at an end surface of the flexible housing. The flexible housing is arranged surrounding the active part via the bore and in contact with the active part. The contact causes a deformation of the flexible housing in a circumferential direction, and the deformation generates a pressure applied on the active part along a radial direction.

Abstract: A device, a method and a system for monitoring an electrical connection status of a disconnector device (110). The disconnector device (110) being connectable to pole-mounted equipment in a power distribution or transmission grid (200), thereby disconnecting the pole-mounted equipment. The connection status monitoring device (100) comprises a determining section (130) configured to determine whether the disconnector device (110) has been activated and to generate connection status indicator data, indicative of whether the disconnector device (100, 110) has been activated. The determining section (130) further comprises a wireless communication section (140) which is adapted to connect to a wireless communication infrastructure (150) using a wireless communication protocol, and to transmit the connection status indicator data over the wireless communication infrastructure (150).

Abstract: A circuit breaker system is disclosed in the present application. The circuit breaker system includes a housing to hold an electrical interrupter within an internal region separated from an external ambient region. The electrical interrupter includes at least a first pair of electrical contact elements that are movable between open and closed positions. A voltage limiter, such as a metal oxide varistor (MOV), is connected across the pair of electrical contact elements to receive and dissipate a transient voltage when the first pair of electrical contacts is moved from a closed position to an open position, thereby reducing undesired arcing and premature wear or erosion of certain electrical components.

Abstract: A monitoring system for remotely monitoring a state of pole-mounted equipment in a power distribution or transmission grid is provided. The pole-mounted equipment includes an indicator device configured to present state information indicative of a state of the pole-mounted equipment. The monitoring system includes a status monitoring device movable via a drive or propulsion system. The status monitoring device is configured to obtain the state information from the indicator device when located within a communication range of the indicator device.

Abstract: Disclosed is a leakage current measuring device for a grid protection system protecting a power distribution or transmission grid from damage in case of a power surge, the grid protection system including a disconnector device and a surge arrester connected in series along a grounding path, the grounding path connecting a phase of a power distribution or transmission grid through the surge arrester and the disconnector device to ground, the disconnector device being configured for being activated in case of an overload condition, thereby disconnecting the surge arrester. The leakage current measuring device includes a leakage current sensor for measuring a leakage current IL flowing along the grounding path, the leakage current IL being indicative of the electrical connection status of the disconnector device. The electrical connection status is one of an activated and an inactivated status of the disconnector device.
