Method for sensing lightning-current parameters at installations having one or more capturing devices and lightning-current diversion paths

Method for sensing lightning-current parameters at installations comprising a plurality of capturing devices and lightning-current diversion paths, in particular for exposed and/or tall buildings, including wind turbines, by using a plurality of sensors on the lightning-current diversion paths to identify a lightning-current event, and comprising

• subsequent evaluation of the lightning-current event and the effect of the lightning-current event on the particular installation,
• characterized in that
• a lightning-current detection sensor is arranged at each of the capturing devices or at each lightning-current diversion path, which lightning-current detection sensor provides a yes/no statement concerning a lightning-current event in relation to the respective capturing device of the respective lightning-current diversion path, wherein at least one lightning-current measurement sensor is provided at a central point of the merging of the lightning-current diversion paths toward the ground, which lightning-current measurement sensor detects both surge currents having a duration of less than 5 ms and long-term currents having a duration of more than 5 ms, wherein furthermore the magnitude of the charge of the particular long-term current that has occurred is determined and used to determine possible effects on the installation, wherein the installation is a wind turbine having rotor blades, a rotor shaft and a hub, and wherein the at least one lightning-current measurement sensor is provided at the rotor shaft.
