Western Link HVDC interconnector makes landfall in Scotland

[Tim Lamb]

Yes. The link points to carbon fibre and exotic aluminium.

Yes , I was getting the sequence mixed up, 132, 275, 400. I never worked on them, just cut trees under them.

Skin effect anywhere?..

That must have been fun on damp days;?..

You mean because of increased risk?

Trees/branches are all categorised depending on distance from conductors , voltage of conductor and what bits might fall on conductor. Any that are too dangerous to be worked on live require a shut down.

At 50Hz?

[Chris Hogg]

I see that there are (or were) actually two UK-Norway interconnects on the table: one, still on the table and progressing AIUI, would come ashore at Blyth in Northumberland,

while the other, back in the cupboard for the moment, would come ashore at Peterhead in Aberdeenshire

This is what NG is using and has been for quite some time now.

And the Belgians

This pdf details the NG strategy on network losses and the increases in overhead line capacity (from page 7 onwards)

[The Other Mike]

The former is most definitely 'on' Contracts were placed for cables and laying and the converter stations some time ago.

Yes oddly enough its usually thought of an RF issue but i seem to remember it was a possible problem somewhere at much lower frequencies.

I thought they ran HVAC lines at higher frequencies. 400Hz seems to come to mind.

Not for the "standard" 275/400 kV "supergrid"

Thanks.

That's in aircraft.

[The Natural Philosopher]

Nah. Not really mate.

Problems of power lines are more interline and to-ground capacitance and resistance and phase shifts, if its long enough. That's why DC.

[The Natural Philosopher]

No.

Never heard of that

[tony sayer]

Indeed I'm buggered if i can remember where that article was it was about a power distribution system where you wouldn't have thought skin effect would be significant but it did turn out to be so. I'll post if a can remember where it was!.
