Measurement of lightning currents on high structures and wind turbines

This article deals with the measurement of lightning current on high structures and, in particular, wind turbines. It offers a synopsis of the special lightning current characteristics for high building structures. The special requirements for lightning current measurements on high objects and, especially, wind turbines, are derived from this. It presents a measurement system for determining lightning currents in wind turbines based on Rogowski coils. In order to verify this lightning current recording unit, comparison measurements were carried out at the lightning measurement stations Gaisberg (Austria) and Peissenberg (Germany). First measurements have also been carried out on wind turbines.
