Abstract
A device is provided for receiving a transmission signal and for transmitting an optical beam having an adjustable intensity, wherein the optical beam effects the transmission signal. A transmitter for transmitting the beam has a controller for setting the intensity. A receiver for receiving the transmission signal has an analyzer for outputting a threshold signal if the strength of the transmission signal exceeds a predetermined limit value. A pick-up outputs a start signal for starting the transmission signal. A control unit is connected to the analyzer, the pick-up and the controller. After reception of the start signal from the pick-up, the control unit sets the intensity at the controller to a value which rises continuously from essentially zero until the analyzer outputs the threshold signal, and then leaves the controller unchanged until reception of a new start signal. A method is also provided for using the device together with a measuring device configured as a transceiver, in an electrical power distribution network.
