OK,
So if a cat can get up there, so can a child.
That power authority needs to review it's anti-climbing protection policy and fast.
The anti-climb policy over here is the same as it is for all DNOs in the UK, which go by the standards set out in the Electricity Supply, Quality and Continuity Regulations. Any amount of anti-climbing measures can be overcome by someone determined to do so, and there is a limit as to how much effort, time and money you invest when you look at the likelihood or risk of harm coming to people. In the UK it is generally covered by the "as far as is reasonably practicable" clause.
The cat did remarkably well to get up that pole, and it was a relatively straightforward bit of network switching to isolate the 33kV line (luckily it happened when the load was fairly low).
I agree with you Trumpy that kites are a big problem - we've had two in the last six months stuck in the lines. I start giving safety presentations to some of the local primary schools next week to try and stop this from happening. Just need to wait for the motorbikes to stop going around the TT course so I can cross the road to get to them!
Cheers
