    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.

    Bibliography:

    Several sources were referenced
    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.

    Hello,

    very old list, there is no more an east and west Germany.
    Germany was reunited 14 years ago.
    Most european countries now have 230 V instead of 220 V.

    Bye

    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.
     
  4. 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.

    Thank you Andrew. I presume Dark Matter means absence of Grey
    Matter. It certainly seems that way.

    **** YOU, TROLL BOY! Take note where he stated that in most places
    it is still as I stated, you retarded ****!

    Also note where I stated that things may be different in a note at
    the bottom of my post.

    You contribute NOTHING. You are on par with a pile of fresh stool.

    Take a hike, dipshit.

    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.

  9. A minor nit-pick - Tahiti is the same as France (ie. 230V/50Hz).. and has
    been for a very long time. You're not even close on this one.

    Hello,

    this list is better:
    http://www.kropla.com/electric2.htm
    But the information is from 1998, there may have been some changes in
    the meantime.

    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.

    ----------
    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.
     
  15. OZ.

    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.

  16. Sorry guys - I've just checked and Tahiti is actually 220V/60Hz.. But it's
    still run by the French! ;-)

    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.
     
  18. 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.
