Tools and methods are provided for scarfing rotor blade segments. A rotor blade segment includes a pressure side and a suction side. A tool includes a first guide configured for mounting on one of the pressure side or the suction side, the first guide including a first curved rail and a second curved rail spaced from the first curved rail. The tool further includes a second guide movably coupled to the first guide at a scarf angle, the second guide including a guide rail extending between and movable along the first curved rail and the second curved rail. The tool further includes a cutting device movably coupled to the second guide, the cutting device movable along the guide rail and operable to remove material from the one of the pressure side or the suction side.

A system and method for performing a continuity test on a lightning conduction system of a wind turbine are disclosed. The system generally includes a testing device having a blade ring configured to be positioned around at least a portion of an outer perimeter of a rotor blade of the wind turbine. A carriage may be attached to the testing device and a cable may be attached to the carriage. The cable may generally extend between a first anchor point and a second anchor point, wherein the anchor points are spaced apart from one another such that a lightning receptor of the lightning conduction system is disposed between the anchor points. Additionally, the cable may be coupled between the anchor points such that, as the cable is displaced, the testing device is moved to a position at which an electrically conductive member of the testing device contacts the lightning receptor.

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.

Lightning protection for wind turbines

A wind blade spar cap laminate repair for wind turbine rotor blades, a repair kit to repair spar cap laminate damage, and a method of repairing damage on wind turbine rotor blades is provided. The wind blade spar cap laminate repair includes a prepared surface, an adhesive region disposed on the prepared surface, and a repair disposed on the adhesive region, wherein the adhesive region sufficiently bonds the repair to the prepared surface to substantially match the mechanical properties of the bulk of the wind turbine rotor blade.
