Hello all.

The world has a few differing domestic electrical standards, 100, 120,
240 volts, 50 and 60 Hz and so on. Industrial customers have yet more.

Distribution via high voltage AC, and now DC in places.

I understand why various areas of the world have these differences - due
to historical reasons, etc.

My question is that if we were to have a brand new electrical system,
common to all areas, what would, or could, it be? Still AC? 300 volts?
Different frequency?

No real reason to ask other than idle curiosity.


There's no complete answer as it depends on the size of the system.
Higher voltage reduce transmission losses.
DC reduces transmission losses too. (But requires more technogly)
Higher frequncys increases losses but makes more compact motors and
transformers possible.

We are in the midst of a technological evolution when our powers systems
will be linked to others abroad far more than at present, micro generation
will be universal and we will have smart grid technology to control
everything.
