Lightning Protection Efficiency and Shielding for Wind Turbine Blades

Nowadays, there are two main types of lightning arresters for wind turbine blades: one is to set the blade tip lightning arrester only at the tip of the blade, and the other is to set the blade tip lightning arrester and the blade body lightning arrester at the same time. However, there is no unified guidance plan for the selection of blade lightning arresters and the arrangement of lightning arresters by various blade manufacturers today. The influence mechanism of the arrangement of lightning arresters on the lightning protection efficiency of blades is still unclear. Therefore, finding a method to characterize the efficiency of the wind turbine blade lightning protection system is the theoretical basis for optimizing the wind turbine blade lightning protection system.
