Why not turn off power grid one hour before hurricane sandy ?

They did perform a preemptive shutdown for the big stuff that was certain to be damaged:

From what I'm reading, it is the distribution substations that are the most time consuming repair, sometimes taking months if the damage is severe enough.

The other miscellaneous damage due to trees, toppled poles, and that kind of thing is nickel and dime and handled on a case by case basis.

snipped-for-privacy@downunder.com laid this down on his screen :

The medium voltage network has to be the same size, it is just that there are fewer, maybe half as many, transformers in the 230/400volt countries.

that.

common.

Where is this documented?

The actual culprit is the natural temperature oscillation between Pacific and Atlantic... right now the Atlantic is increasing in temperature and the Pacific is cooling... bye, bye East Coast ;-) ...Jim Thompson

While true it is probably meaningless as it would take about 12 hours to do in a coordinated way. And the customers just ain't gonna stand for that.

Never on the same mission. The pinks only track nutjobs. :)

they make up for the lack of transformers with piles of electrocuted bodies in places with dangerous voltages to the home.

Nonsense. We are more careful than that. It appears our deaths by electrocution is a bit lower than the USA.

And a lot of US machinists would love to get 3 phase to their workshop. Almost anyone can get good clean 3 phase 400 volts here in Aus.

they aren't in europe.

3 phase isn't rare in the US at all. Is it something run to home? no, because there's no need for it.

Yawn. RPC are simple as dirt to build. I've seen them in use for over 45 years.

In Finland there are 0-5 fatalities electrocution each year (population over 5 millions) including all voltages. Half of this happens to professionals, often with 20 kV medium voltages, lorry etc. drivers hitting overhead lines. Some have been killed by climbing on stationary trains and electrocuted by 25 kVac.

I counted less than a dozen fatalities at home from 230/400 V during the whole beginning of this century.

I have seen applications where "backhoe fade" was the number one failure mode in both frequency and severity.
