GWO Blade Repair Training Standard V2.0
2021-04-01_TS_BR_V2
Training staff shall:
Give constructive feedback on the participants’ ability to locate, identify, categorise and document damage on a wind turbine blade – both on the blade itself and from a distance, using visual inspection, tap testing, a telescope and a camera with a zoom lens
INSPECTING LIGHTNING PROTECTION SYSTEM
50 min.
The aim of the lesson is to give the participants the ability to measure lightning receptors, and to learn how damage to on lightning protection system components can be identified..
After successfully having completed this lesson, the participants will be able to:
Take responsibility for measuring lightning receptors and identifying damage to lightning protection system components (Ability, intermediate level)
SURFACE COMPONENTS
Learning objective:
The participants can explain the function of typical surface components of a lightning protection system (Knowledge, intermediate level)
Training staff 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
The participants shall:
Explain in their own words and 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
Training staff shall:
Give constructive feedback on the participants’ above explanations
