Blade Repair Standard / V4 2023-05-02
Give feedback on the participants’ abilities to identify damaged components of the lightning protection system by conducting a visual inspection
The participants shall:
Practise the ability to identify damaged components of the lightning protection system by conducting a visual inspection
ELEMENT 22.3 - MEASURE RESISTANCE
Learning objectives:
204) The participants can perform safe measurements of the conductivity and resistance of a typical lightning protection system using a low-resistance ohmmeter (Skills, intermediate level) 205) The participants can take responsibility for safely using a low-resistance ohmmeter to measure the resistance of the lightning protection system and to identify a defective lightning receptor (Ability, intermediate level)
The instructor shall:
Describe the tools required for measuring the resistance of the lightning protection system
Explain the safety precautions to be adopted for using a low-resistance ohmmeter
Explain common procedures to ensure correct reading and direct contact between receptor surface and low- resistance ohmmeter (e.g. cleaning the receptor) Demonstrate how to safely use a low-resistance ohmmeter to measure the resistance in the entire lightning protection system Demonstrate how to safely use the low-resistance ohmmeter to identify which lightning receptor or section of cable is defective
Facilitate practice to improve the participants’ ability to:
a. safely use a low-resistance ohmmeter to measure the resistance of the lightning protection system
b. safely use a low-resistance ohmmeter to identify a defective lightning receptor
Give feedback on the participants’ ability to safely use a low-resistance ohmmeter to measure the resistance of the lightning protection system and identify a defective lightning receptor
