ABSTRACT:
A rotor blade for a wind turbine is provided. The rotor blade includes a rotor blade body, at least one receptor adapted to be a location for lightning impact, and at least one down conductor connected to the receptor and located within the rotor blade body. The down conductor includes a first conductor connected to the receptor and a ground connection of the wind turbine, and a second insulated conductor connected to the receptor and a non-grounded location of the wind turbine. A path is formed from the ground connection of the first conductor to the non-grounded location of the second insulated conductor. This path facilitates a continuity test used to evaluate a condition of the lightning protection system.
