Curious as to what is being used where? Here's a list!

Voltage tolerances are the standard plus or minus10%, but the
underdeveloped nations on the list can vary to a greater degree, and
typically do.

Frequency tolerances are defined more locally to their geographical
region, but again, non-industrialized nations are where the greatest
deviances are found.

Since the data is not of a proprietary nature, there is no need to
reference them, however, they can be provided upon request.

Also, infrastructure changes in some nations may have changed their
power schema, though it is not high in likelihood.

For most third world, and developing countries, electrical service
is a relatively new part of their infrastructures. In some locations
multiple developments could have been put in place, and some cities or
buildings have multiple generating providers and distribution systems,
and schemas for service. Voltages given in the table are the most
common in use for each country.

No shit, but their electrical infrastructures are likely to be the
same, and are referred to with the old segratatory lines, even if the
grids have been hooked together since. You should post the CURRENTLY
used schema, if it is different, for either or both.

And yes many Euro nations have gone up from 220 to 230 and some went
down from 240 to 230, the new int. std.

But your "most" remark is kind of vague. If you have an updated,
corrected list post it, don't just mouth off half assed about it.

I think all CENELEC countries are 230V now (which is all the EU,
and more besides). The tollerances vary though, and in all cases
include their previous nominal value (but not necessarily the
extremes of the previous tollerance limits). There was an interim
period which was supposed to be from 1995-2002 where all former
220V countries became 230V +6%/-10% and all former 240V countries
became 230V +10%/-6%. All the EU (and maybe all CENELEC -- not sure)
was due to become 230V +/-10% tollerance at the beginning of this year,
but that has been postponed as many countries couldn't do it in time.

In practice, most peoples' mains voltage in these countries as
measured is unchanged, but goods have to be manufactured to cover
the whole range, as part of the open market between EU countries.

--------------------------------------------------------------------------
At this point, I notice the first error. Canada is 120V/60Hz and has been so
before the US effectively standardised to that level. Further on, I notice
the same thing that has been mentioned by others- that is the EU countries
are now standardised to 230V 50Hz.
For your information Albania (unknown on your list) is nominally 220V/50Hz
and Australia is now officially 230V/50Hz.

I also note that this information in your list has been asked for and given
many times in the past using the on line reference http://kropla.com which
keeps up to date and is used by Fodor's for their information. This site
also includes information on the type of plugs used in the different
countries as well as other information for travellers such as TV standards.

Your effort is appreciated and the variations you have listed are generally
within tolerable limits as indicated by Andrew Gabriel.
Also even though standardisation exists, in many regions the standards are
wish lists rather than practice.

Hello,

the power grids of the former east and west Germany were coupled
together in 1995. In september, there were 3 power lines between the
former parts, a fourth line followed later. The introduction of 230 V
instead of 220 V was started also 1995 in both former parts of Germany.

Still 240 in aus at the moment, hasn't changed just yet. 250 is no
longer used as the nominal voltage though, pity really would have been
better to make it all 250 volts instead of dropping it.

Most times Ive measured voltage around the place, its often close to
250. Distribution transformers are usually aimed at 433 output (250
single phase) to give a nominal of 240 volts to the consumers.

Western Australia I think used to have a nominal voltage of 253 volts
(from 440 volts 3 phase) though on paper its now 240 like the rest of
the country. Im told the voltage at power outlets there ccan still be
up around 260 volts, which is getting kind of high.

The change got delayed a bit, I think we change in 2006 or something.

Out of interest, is the US planning on changing to 115/230 from
120/240?
----------
My source (kropla) indicated 230 as the new standard in OZ but also did
indicate that many parts are still using the old 240 standard (to be
different from the Pommies?) . It appears that the change is upcoming rather
than in existence.If it is in error, I apologise. I do note that whether
you use one or the other, they are both within the 6% margin allowed in OZ.
Regarding 250 vs 230V - it is cheaper and easier to march in step with (most
of) the rest of the world (North America being the main exception).

As to the US-to the best of my knowledge it is 120/240 and has been that
for some time.

Don, you are quite correct. Down Here we are still officially using 240V
(and up to 260V at the end of long service lines under no-load conditions!)
but a change to 230V is coming, mainly driven by manufacturers refusing to
make higher-rated equipment when the European 230VAC is not that much
different.

In fact, most new appliances for sale in Oz are only 230V rated - they just
don't tell the customers - because, as you said, 230V is within the 6%
margin.

If one looks the list over, one can immediately see what occurred
post WWII.

The Brits, and the US split up nearly every locale that saw action.
As each nation was industrialized, nearby nations, and the nation
supplying the assistance surely played a hand in the decisions for
arriving at a schema in each location.

It is easy to spot those that followed the Russian schema as well.


Tahiti doesn't follow the "French" standard as they did not have
one, in that they themselves *follow* a standard which they themselves
did NOT author.

Other "rifts" are apparent as well.

A LOT *has* changed since the data was compiled, as I stated in the
post.

Goes back way before WWII -- I don't think there have been many
significant changes since WWII except small voltage adjustments.
British system is used in most of the former British Empire countries.

-----
Andrew - you are absolutely correct. In fact it goes back before WWI to the
colonial era. -"sun never sets on the empire...."etc. time. It happens that
the major population regions of the world were affected more by the British
or European countries than by the US. The main exception is Canada which
stayed with the neighbor to the south in this respect.
I note that GEC or ALSTROM have had a greater impact world wide than GE or
Westinghouse. I also note that such outfits as Siemens, ASEA, Brown Boveri,
etc - all good European outfits have made inroads in the North American
market (admittedly mostly after WWII) because what they had to offer was
better in many situations.
There is a tendency, in this group, to think that all innovations and
advances originate in the US. 'Tain't so.

An example is in the development of high voltage, high interrupting capacity
circuit breakers -look up old AIEE papers on air blast breakers and the
discussions (i.e. fights) which are more intereating than the papers
themselves.
