Fact, Fiction or Uneducated Comment?

Just read 'Moving the goal posts' in May issue of Forestry Journal, According to Hugh Jones they are erecting goal posts to mark overhead conductors (good idea) but he rekons they are using wood as one of the materials as it is NON conducting? any comments?? is wood not porous?

Well that was my understanding when I did my AE units, that was a few years ago, so things might have changed re: ohms law and conductivity?

Wouldnt be my first choice but surely what they have in mind must have beem tested and MUST work?

 

 

The potential for it to go wrong is pretty high, It will hit the fan big time if it does

If they are marking "safe" heights and distances, there should not be an issue what they are made of.

Exactly, they will be used to tell you how high you can go without risk of it arcing across to you.

Thats how i understood it

I guess tha goal post are there to show the "safe area", and will therefore include a nice margin of error / distance.

 

It would be a bit pointless if they were positioned at exactly the point where things got, shall we say, interesting.

 

I shouldnt think it wouldn't matter of they were made of metal (just like the trucks passing beneath them)

But surely PVC can get wet?
