Induction would be one way to do it. The fault detection devices hung on the cables, which can also show flashing lights to guide repair teams to a fault, are powered that way.
Read the full replyI was driving home in the dark the other day and noticed some pylons with flashing red beacons on top of them.
I got to wondering how they were powered. Obviously no shortage of nearby power but probably not the right kind of easily accessible power just to power up a beacon. Anyone know how it?s done?

Agreed, although the electric field at ground level is also enough to make a 6 foot fluorescent tube "strike", if it is held vertically.
Filling gaps...
I can feel the buzz on my metal white cane when I'm near a pylon, but I am not sure about enough current to supply a bright flashing light on every pylon. Were these on top of a hill?
You might, on close inspection find its just a boring connectionto the mains underground somewhere!

Unlikely, I think.
Back in the days before GPS, a friend of a friend took out one of Heathrow's "radio" navigation beacons when they had a JCB man in to dig a swimming pool. The driver didn't even notice.
Miss October is a stunner:-)
I've seen lots of these in France
