A method of installing a lightning protection system can include forming a blade wall of a wind turbine to at least partly include a socket. A part of the socket can be removed, after forming the blade wall, to provide an opening through the blade wall. A receptor plug and a receptor element can be secured to the socket at the opening.

Lightning protection system and method for wind turbine blades

Tip receptor mount for lightning protection systems

A lightning protection system can include a socket, a receptor plug, a tip receptor, and a tip receptor mount. The socket can extend at least partly through a blade wall, and can include a socket body, a first retention shoulder, and a plurality of first teeth. The receptor plug can include a plug body, a plug conductor, a second retention shoulder, and a plurality of second teeth. The first retention shoulder can engage the second retention shoulder to secure the receptor plug to the socket. The first plurality of teeth can engage the second plurality of teeth to resist rotation of the receptor plug. The tip receptor mount can include latticed bonding wings that can be secured to a wind turbine blade with bonding material. The receptor plug can be accessed to be secured to the socket via an opening in another socket that is formed into the blade wall.

A receptor assembly for lightning protection of an object, such as a wind turbine blade, includes a receptor disk configured to be placed on a surface of the object, a receptor block insulator with an integral receptor block, a cover that engages the receptor block insulator, and a cap that engages the cover. The receptor disk and the receptor block may be made of electrically conductive materials, and the cover, and the cap, and the receptor block insulator may define a chamber among them that is lined with an electrically-conductive coating sandwiched between relatively high dielectric media to electrically isolate and shield internal parts of the receptor assembly from receiving a lightning strike directly.

A grounding lug for holding a grounding wire includes a housing defining an opening for receiving a wire and a clamping pad movable relative to the housing. The clamping pad is movable between an unclamped position in which the clamping pad defines a wire-receiving pocket in combination with the opening defined by the housing, and a clamped position in which the clamping pad clamps the wire to the housing. The grounding lug also includes a moving mechanism coupled to the housing and the clamping pad for moving the clamping pad between the unclamped and clamped positions.
