Hello, So I have a question about electric power lines. Today I was under some large power lines and I noticed some ticking noises. I had never noticed this noise before and was curious I thought maybe the current flowing through the lines was too great, and the lines were arcing to each other. but that seems silly. Could anyone help me out? thanks! Note: they were the large lines that run through the large metal tower structure, not the ones along the road... If that changes anything.
