Abstract
A system and method for automatically inspecting a lightning protection system on a wind turbine is disclosed. The system and method may include a wind turbine having a plurality of blades mounted to a hub, a lightning receptor on each of the plurality of blades, a lightning protection system extending from each of the lightning receptor to an earth grounding grid and a conductor that is part of a testing system extending from at least inside the hub, through the inside of at least one of the plurality of blades and connecting to the lightning receptor, the conductor completing a circuit extending from the lightning receptor to the earth grounding grid. A test current signal may be introduced into the testing system for a leg of the lightning protection system to be tested and an electrical continuity in the circuit using the test current signal may be determined.
