Title: METHOD FOR SENSING LIGHTNING-CURRENT PARAMETERS AT INSTALLATIONS HAVING ONE OR MORE CAPTURING DEVICES AND LIGHTNING-CURRENT DIVERSION PATHS
Abstract:
The invention relates to a 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. According to the invention, a lightning-current detection sensor is formed on each of the capturing devices or each lightning-current diversion path, which lightning-current detection sensor provides a yes/no statement concerning a lightning-current event with respect to the particular capturing device or the particular lightning-current diversion path. Furthermore, 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 at least one 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 is used to determine possible effects on the installation.
