Power Lines

I work near power lines. They’re above the parking lot. When I walk through the parking lot, I hear them buzz and crackle. Why do they crackle and buzz? What’s really happening up there? Specifically, what causes the crackling sound? I suggested to a co-worker that it might be arcing, but he was skeptical, since that’d be an awful lot of power being wasted.

Here’s a picture of the power lines I took on a walk a couple weeks ago:

    I’ve always assumed it was some sort of arcing, but if that’s the case, why don’t we see it flashing at night? This bears further investigation.

    Better late than never… Probably hearing the corona discharge… It may not be visable…
