I've witnessed those lines taking lightning strikes and saving the grid they were on from outage.

So... it seems to me that there should also be a "cone of protection" from these lines. We live in Chitty Chatty which has a high tension set of lines running right down the middle of the village. Is it reasonable to imagine the protection on those towers provides a cone of protection for nearby homes? If so, to what distance?
One model shows Protection @45 degrees from perpendicular or for a distance equal to the height of the ground wire.

Another model would use a 150 ft diameter arc tangent with the wire and the ground.

Unlikely homes are that close.
