Pylon of the Month - February 2018

20170905_133727

A belated Happy New Year to pylon fans everywhere, but especially to those in Sweden, because that's where February's pylon comes from.  We've had some amazing photographs recently, but I like to keep things real and so this month's pylon is a welcome return to the 'pylon pictures taken from the window of a moving vehicle' category. The last time one of these featured was back in January 2015.  The picture arrived with this message

The pylon design is not common here in Sweden, but I find it quite beautiful. It, and one like it, are placed by the road Norrortsleden in Täby just north of Stockholm. 

There was even a link to Google maps where you can see the pylon (and it's shadow).

If you happen to be in Sweden and February's pylon (plus it's nearby twin) isn't enough, then there is a chance to see two truly unique pylons.  Here is the low down:

East of Stenkullen in Sweden there are two electricity pylons which are unremarkable when you look at them but they are unique in the world of electrical inventions and devices. The Konti-Skan, a high-voltage direct-current transmission line that runs between Denmark and Sweden is the only electricity pylons in the world that carry both AC and DC circuits.

Transmitting electrical power using Direct Current (DC) electricity might seem a bit strange if you are thinking back to school physics lessons with transformers and Alternating Current (AC). If that's the case, you need to find a friendly electrical engineer and ask them to give you a few lessons on HVDC. The key point is that it can be more efficient over longer distances, but it also allows power transmission between unsynchronized AC transmission systems. If my understanding is correct that is the key issue here when the link is between two different countries (Denmark & Sweden) but perhaps I need to find myself a friendly electrical engineer to check this. That's all for now folks.
