Suggestion: The final red arrow needs to have the word 'SOMETIMES' written upon it.

 

What i have been asking for several years is:
The NGCP 69kv system runs on steel towers (see above dwg).
Each distribution utility has some wooden poles.

If they are removing some wooden poles, WHY WHY must the entire 69kv system be shut down for a half million people when a properly designed / maintained / operational isolation system could allow 80% of "consumers" to remain with power, and ALL THE CREWS CONCENTRATING ON ONE AREA of wooden poles ????

Or is that too complicated for the Distribution Utilities to coordinate. And anyone who says, "oh thats NGCP's problem" deserves to sit in the dark.

 

You are making this assumption based on a cartoon? This is the only evidence you have to support your argument that all of the NGCP distribution system is on steel towers. This over their statements that the NGCP is replacing wooden poles.

Are you assuming things? Are you being arrogant?

 

i'm guessing 69kv lines aren't running on wood.
if i'm wrong, i profusely apologize, no-one ever corrected me in the past.
if guessing is arrogant, i profusely apologize, and will try to STFU from now on.

 

So you are assuming. (suppose to be the case, without proof)

Why put the rest of us in a position to correct your assumptions? You can do your own internet searches.

From wikipedia:
Subtransmission lines carry higher voltage power from regional substations to local substations. They usually carry 46 kV, 69 kV, or 115 kV for distances up to 60 miles. 230 kV lines are often supported on H-shaped towers made with two or three poles. Transmission lines carrying voltages of above 230 kV are usually not supported by poles, but by metal pylons (known as transmission towers in the US).
https://en.wikipedia.org/wiki/Utility_pole
The 69 kV "subtransmission" lines here are less than the "above 230 kV are usually not supported by poles, but by metal pylons"

Thank you

 

Surely you are correct though that such a vast area should not be affected by work taking place in a localised area and there should be some system to prevent this - I am not aware this happens in the UK, for example.
