I read in !emc-pstc that Rich Nute <ri...@sdd.hp.com> wrote (in <200311110043.qaa01...@epgc264.sdd.hp.com>) about 'EN 61000-3-2:2000' on Mon, 10 Nov 2003:
>The standard was written and promulgated to the IEC by a European >committee No, it was developed in IEC SC77A/WG1, which had experts from all over the world. It's true that some were not as diligent in attending to the work as they might have been, but that is hardly the fault of the diligent members. >to solve an >anticipated European voltage distortion >problem. At that stage (around 1989) it was not known whether the anticipated problem was confined to Europe or not. We now know that Japan also has a problem, but the main problem in USA is hot neutrals rather than voltage distortion. There are problems with harmonics in Canada, but it isn't clear that they are mainly due to low-power equipment, AIUI. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?
