An intresting earthing installation

[Graham.]

I pass by this place most days, and it occurs to me it might be unique in this particular context.

Does anyone know of anything similar in a publicly accessible area?

On Google streetview, that's just off Glenmere Close, Bury New Road in Prestwich.

Until photo DSCF2230, it was sort of a "Kin yer tell what it is yit" competition!

[Graham.]

I considered initially posting 2234 as a quiz question.

[Graham.]

It comes under Bury LA.

Is it all connected down a single pole, or are there multiple poles?

[Graham.]

The forecourt was there for many years under those lines without the protection, so I suspect:

a) The regulatory requirements were subsequently tightened b) The site could not have been built there now.

[Graham.]

That's my reason for posting. You did notice the HV power lines?

I don't *think* they are expecting an arc from the lines, I imagine its more like a faraday cage to keep induced voltages/currents out.

I expect that its tied up with the Petroleum regs supply and storage regs somewhere.

I doubt lightning would be a problem, leakage under very damp conditions might be but I'm bu^^ered if I'd like to live under that lot!!..

Looking at that map there was a very odd incident in that area IIRC a railway tunnel, long abandoned, collapsed in one day back in the early

50's and took the lives of the sleeping inhabitants!..

So prolly the wires are less dangerous;!..

[Andy Burns]

More likely than the cables falling, I suppose.

Although I live in the countryside, I've got a line of 400kV power lines about 1/4 mile away*. One of the public footpaths across a field passes under one of the runs, mid-span, where the cables are at their lowest. They seem low enough to reach up and touch, but are probably at least 60 feet up. Even in dry weather, if you stand underneath, you can hear the electrical discharges randomly ticking away. It's worse when it's wet or foggy. I have to admit, I don't hang around there for too long.

*When it's raining or foggy, they wipe out reception on the lower HF amateur bands (can be up to S9+40 on 160m).

It is, however AFAIK there is an off the shelf petrol station solution certainly used by BP whereby it is integrated into the overhead roof gantry. So could it be someone goofed and had to do a retrospective modification - perhaps the station predates the regs or pylons?

Anything with slot apertures is never a (designed) Faraday cage.
