Why Do Overhead Wires Grumble

Overhead Grumbles

It only seems to happen when it is misty or foggy, never if it is raining. The overhead power cables crackle away to themselves and they can be quite loud about it. When they cross the canal there are plenty of signs telling people not to fish, but I have wondered, probably too creatively, if it is safe to walk under them in this condition; is there a chance you could disappear in a big flash and cloud of smoke? I suspect it would be a good idea to find out a bit more about electricity! Being at a bit of a loose end, I recorded this and you can just hear the grumbling wires above the sound of the M25 motorway. https://youtu.be/Xis8yB7PNv4

I know that my husband could not walk under them, because he has a hypersensitivity to electromagnetic fields. He gets immediately a bad headache and a sense of nausea.

@Ronrybs We cannot even use the wi-fi in the house and no cellphones in the bedroom where we sleep. It's a serious problem.

I've never heard of this before. I wonder why it is? Or has someone already told us in the comments? I never manage to read the comments first. :)

this happens often due to weather too.

I looked it up and the answer is a lot of big words,,,all to do with energy..go figure. When I was a kid in the 50's and 60's people moving out of the cities were told not to build a house under the power lines... we moved to the country and built our house so it was not under the power lines although the high power lines were across our land. The back end of 7 acres when we built. I heard that sound often and knew it had to do with the energy flying through those lines.
