Hello, >> AFAIK many countries in Europe used 220V or 240V (eg, in Hungary we >> still name it as "220" even if it's not that anymore and we know >> that). So (again: AFAIK) 230V was introduced as it was some kind of >> "common ground" between these two values. I am not sure if 230V was >> used before, or really it is just a "meeting point" between the used >> 220 and 240. Yes, the 230 is a new value in the middle between the older used values 220 and 240. > Yep, that's right. The UK used to be 240v while the rest of Europe was > largely 220v. In around 2008, it was all harmonised by doing precisely > nothing. :-) The standard EU voltage is now 230V with a tolerance of > -6% to +10% which allows from 216v -> 253v. No, only in transition period the new asymmetric tolerance is defined in the direction to the old value as 10% (plus 4%) when the value is defined nominally as 230V. The other and the now defined tolerance is and was 6%! Have a look at http://en.wikipedia.org/wiki/Mains_electricity. Old value 220V (+/-6% or 207..233V): in transition 230V -10%/+6% or 207..244V, now 230V +/-6% or 216..244V Old value 240V (+/-6% or 226..254V): in transition 230V -6%/+10% or 216..253V, now 230V +/-6% or 216..244V Martin Message was sent through the cbm-hackers mailing listReceived on 2012-05-19 20:00:12
