HVDC converter

 * ... that a single HVDC converter can convert up to 2 thousand million watts of electric power from DC to AC, enough to boil nearly a million kettles?


 * Symbol possible vote.svg Long enough and new enough for DYK. Looks like a quality technical contribution, although I have to AGF on the offline sources. New DYK contributor does not need to do a QPQ review.
 * However, to qualify for DYK, the article needs more footnotes (we aim for at least one footnote citation in every paragraph, so readers can determine where the content comes from). Several long subsections of this article lack footnotes right now. This paper that I found online looks like a possible good source for some of the content about history of converter technology and what types of converters were used on some past projects.
 * Also, there are issues with the hook. The fact is in the article (in paragraph 1 of the lead section), but the wording in the hook doesn't appear in the article. The article refers to MW, not watts; the article discusses "power rating" and does not use the simpler "can convert" wording; and the article doesn't describe the capacity in terms of the power requirements of kettles. It should not be difficult to revise the hook so it qualifies, if the article footnoting situation can be resolved. --Orlady (talk) 16:31, 19 December 2012 (UTC)
 * Thanks. Not having done this before I didn't realise the wording of the hook had to be as literally close to that of the main article. I should be able to sort out that. Thanks also for the very interesting article (although it does contain errors, for example the statement that the 1961 Cross Channel scheme was built by GEC and CGE Alsthom, when in fact it was built by ASEA.  GEC and CGE Alsthom built the much larger 2000MW scheme that replaced it in 1986.)
 * By "footnotes" I assume you mean inline citations. There are certainly more that I can add, although one per paragraph will be a challenge unless I re-use some of them two or three times.  I'll give it a go anyway.Clampower (talk) 19:06, 19 December 2012 (UTC)
 * The hook wording need not precisely mirror the article, but if there are facts in a hook (such as the watts needed to power a million kettles), those facts need to be in the article. Also, we can't assume that readers will automatically equate megawatts with watts.
 * Yes, when I said "footnotes" I meant inline citations. There is absolutely nothing wrong with re-using a citation multiple times. Some pages use the same citation dozens of times. The objective is to tell where the Wikipedia article content comes from. --Orlady (talk) 22:41, 19 December 2012 (UTC)
 * I have re-worked the opening paragraph so that the wording reflects that of the hook, and added more references. Every paragraph now has at least one reference and some of them are now available online.Clampower (talk) 11:44, 20 December 2012 (UTC)
 * Pictogram voting keep.svg Nice work -- you've enhanced what was already a very nice article! Everything looks good. Still, I'd prefer a small rewording of the hook, to get away from the large-number terminology ("thousand million" doesn't translate well between the different forms of English) and to add some wikilinks:

 * ALT1 is fine with me. Thanks.Clampower (talk) 09:21, 22 December 2012 (UTC)
