Abstract: A device for high-voltage or medium-voltage technology includes at least one connection configured for connection to a high-voltage or medium-voltage conductor; a sensor system configured to determine a plurality of different physical and/or chemical measurement values relating to the device and/or the conductor and/or the surroundings; and a communication system, in particular a wireless system, configured to receive the measurement values from the sensor system and to transmit them to an entity in a network. A method for high-voltage or medium-voltage technology is also provided.

Abstract: An arrangement for feeding electrical power into an AC grid includes a multiplicity of feed modules. Each feed module includes a converter module for converting a direct voltage into an alternating voltage, as well as a storage module for storing electrical energy. The storage module is connected to a direct voltage side of the converter module and an alternating voltage side of the converter module is configured for connection to the AC grid and/or to at least a further one of the feed modules, so that on the alternating voltage side the feed modules form a series circuit that can be connected to the AC grid. At least one of the storage modules is configured for connection to an energy generation plant.
