Abstract
A condition monitoring device for a lightning protection system (LPS) of a wind turbine blade, wherein the condition monitoring device is mountable to a wind turbine. The device includes, a signal generation unit configured to generate and input probe signals into a protection unit of the LPS and/or to at least one tower conducting unit. The device includes a measurement unit configured to detect response signals, which are a system response of the probe signals via a wireless coupling between the LPS and the tower conducting unit. A control unit is configured to control the signal unit and the measurement unit and to process the response signals.
