They cancelled the marathon. Holy crap. What took them so long? Where
were all the thousands of people going to eat? Sleep? Buy gas and
essentials? To let it go so far was just a reflection of the state of the
governments. All of them. Imbeciles.

The death toll is yet to be set. There will be death in the gas lines. In
the looting. In the coming cold. It ain't over until it's over, and that
is a good way off at this pace. They could have already had 2800 houses lit
up with the 7 generators they have at Central Park for the Marathon.

How? Are they going to build a specail substaion to upconvert the
voltage? How do they isolate those 2800 homes from the grid?

Un Believable.

Yes, you are.
Isolate from the grid is simple. Pull fuses or cut wires. Upconvert
is no problem at all. connect generator to the low voltage side of one
of the transformers and it is upconverted to high voltage on the other
side, and stepped back down for the houses on the next transformer. 7
generators can connect to 7 subsegments isolated from each other and
the grid by pulling fuses (or throwing switches, depending how the
particular local grid is set up)

Great way to smoke those transformers. He's talking about 400 homes
per generator. Around here that's 200A service per home, and if they
are using electric heat they will be using a lot of that. What pole pig
will let you feed that kind of current into the secondary?

It was done during/after the big ice
storm in eastern Ontario. Big locomotive sized deisel generators
hooked up to run entire small towns.
We don't have pole pigs in my neigbourhood - Ours are in vaults
underground. There ARE pole pigs around in some other local areas.
but how big are the generators. And also, what voltage? Could
perhaps connect at a substation.

I've NEVER seen a substation handle any 240V, other than to power the
monitor equipment. They drop the HV distribution to medium voltage, to
feed the sistribution transformers. He claimed that seven generators
would power 2800 homes. That's 400 homes per generator, and even if
each home only got 50A average, that 2,000 A at 240 V. Where would they
find fuel for them?
