    Abstract: A blade root cover segment suitable for fitting to a wind turbine blade to span a gap between the blade and a spinner cover. The blade root cover segment includes a first end and a second end and comprises: a curved flange for abutting against a correspondingly curved surface of the wind turbine blade; a cover wall extending radially from the flange; and a tensioning band associated with the flange. The tensioning band comprises a first end proximate to the first end of the blade root cover segment and a second end proximate to the second end of the blade root cover segment, and wherein the first end and the second end of the tensioning band include connection means for connecting with and applying tension between a like blade root collar segment. The invention also encompasses a blade root cover comprising a plurality of blade root cover segments. The invention also extends to a method of assembling a blade root cover from a plurality of blade root cover segments.

    Abstract: The present invention relates to a lightning current transfer system (100) adapted for usage in a wind turbine (W) having a hub (20) that is rotatably supported relative to a generator in a nacelle (30) and a plurality of blades (10) that are pivotably connected with the hub, wherein the hub (20) is covered by a spinner (20A). The lightning current transfer system (100) comprises a blade band (10A) mountable to the root of the blade (10); a lightning ring (80mountable to the spinner (20A) facing the nacelle (30); a first contact device (70) mountable to the spinner (20A) adapted for providing lightning current transfer from the blade band (10A); a connecting device (75) for connecting the first contact device (70) with the lightning ring (80); and a second contact device (30B) mountable to the nacelle (30) and adapted for providing lightning current transfer from the lightning ring (80) to ground.
