Abstract: A wind turbine blade is described having a lightning bypass system located at the root end of the blade. The lightning bypass system comprises a stay bolt formed from an electrically insulating material having a conductive core. The conductive core of the stay bolt provides a conductive path for a lightning down conductor system through the root end of a wind turbine blade to the turbine hub or nacelle, bypassing any sensitive root end components of the wind turbine blade.

Abstract: A wind turbine blade is described having a lightning protection system, wherein the lightning protection system is arranged to protect conductive elements or modules used in or on the blade. In one aspect, the lightning protection system comprises a conductive band to be arranged around the circumference of the blade at the location of an internal conductive module, to prevent a lightning strike from penetrating the blade and potentially damaging the internal module. In another aspect, the lightning protection system comprises a lightning down-conductor having a signal-carrying structure, e.g. a signal cable, power cable, or a waveguide, integrated into the down-conductor. In a further aspect, the lightning protection system comprises at least one lightning receptor arranged to protect externally-mounted antennas from lightning strikes.

Abstract: A wind turbine blade is described having a lightning protection system wherein a lightning down conductor is conductively coupled to at least one blade root bushing provided at the root end of the blade. The use of the blade root bushing as part of the conductive path of the lightning protection system allows for a structurally sound and reliable connection of an internal down conductor to an external lightning protection system and/or to a suitable ground connection at the blade root end.
Abstract translation: 描述了一种具有防雷系统的风力涡轮机叶片，其中避雷针导体与设置在叶片根端的至少一个叶片根部衬套导电耦合。 使用叶片根部衬套作为雷电保护系统的导电路径的一部分允许内部下导体与外部防雷系统的结构上可靠和可靠的连接和/或在叶片根端处适当的接地连接 。
