I was wondering whether there UV flash also exist for DC transmission lines. Is there any expert around who knows that?
This is of interest as it is very difficult to build new power lines all over Europe, usually resulting in around 20 years of legal battle for a mere 30 km of power lines far away from any densely populated area. This is just slightly reduced for buried transmission lines with all their disadvantages. Thus a current idea/discussion is to hang DC power lines on existing poles for long distance transmission.
