Main Question or Discussion Point
Hello, I was recently onsite in the Philippines and the equipment owner stated their wind turbine had been hit by lightning. The only obvious damage was to the bolted connections at the root of one blade. One was sheared, the other bent. Does anyone have any experience of lighting causing this type of damage? The blades appear to have no more than normal wear from 6 years of age and once we got the PMG back to our workshop it still reads a voltage.
