Abstract: A disconnector device is connectable to pole-mounted equipment in a power grid. The disconnector device is activated in case of an overload condition, thereby disconnecting the pole-mounted equipment. The disconnector device comprises a passive radio device to be enabled via an incoming radio signal. The passive radio device, upon being enabled, transmits, in at least one state of the disconnector device, an indicator radio signal indicative of the respective state of the disconnector device, the state being one of an activated state and a deactivated state of the disconnector 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.

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

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: The present invention relates to a method for combined administration of carbon monoxide (CO) to an ex-vivo fluid and monitoring of the carbon monoxide administration, said method comprising: (i) generating CO by reacting a CO releasing molecule (CORM) with a release triggering molecule; (ii) administering CO to an ex-vivo fluid by contacting the ex-vivo fluid with the CO generated in step (i) via a gas-permeable membrane; (iii) analyzing carbon monoxide and/or a carbon monoxide marker after administering in step (ii) CO to the ex-vivo fluid by complementary monitoring techniques; (iv) adjusting the CO administration based on the analysis of the carbon monoxide or the carbon monoxide marker carried out in step (iii), if necessary. It furthermore relates to an extracorporeal circuit system for use in the method of the invention.
