Blade Repair Standard / V5 02052025
200) Take responsibility for measuring lightning receptors and identifying damage to lightning protection system components (Ability, intermediate level)
ELEMENT 22.1 - SURFACE COMPONENTS
Learning objective:
201) The participants can explain the function of typical surface components of a lightning protection system (Knowledge, intermediate level)
The instructor shall:
Explain the reasons for having a lighting protection system in a blade by considering the effects of lightning current on fibre-reinforced composites and by showing examples of damage caused to a blade by lightning current
Describe typical components in a lightning protection system, such as lightning receptors, lightning cable, and the connection to the hub
Explain how the lightning receptors connect to the lightning cable, and how they conduct lightning current from the surface of the receptor to the lightning cable and out of the blade
Ask the participants relevant questions about the function of the lightning receptors in a wind turbine blade, and how lightning current is conducted from the surface of the receptor through the lightning cable and out of the blade
Give constructive feedback on the participants’ above explanations
The participants shall:
Share their understanding of the function of the lightning receptors in a wind turbine blade, and how lightning current is conducted from the surface of the receptor through the lightning cable and out of the blade
ELEMENT 22.2 - VISUAL AND CONDUCTIVITY INSPECTION
Learning objectives:
202) The participants can copy how to carry out a visual inspection of the lightning protection system (Skills, basic level)
