Single-phase transformer


I created this and thought it might be worth a try here. Theajiii

diagram is currently illustrating transformer and shows the magnetic flux linkage in a stylised single-phase two-winding transformer.


 * Nominate and support. - BillC 20:00, 30 December 2005 (UTC)
 * Support. A nice image, illustrating the article very well. -- Vidarlo 23:54, 30 December 2005 (UTC)
 * Oppose, great diagram but very boring. Needs some color. Neutralitytalk 04:56, 31 December 2005 (UTC)
 * Oppose, as per above. Neutral for the colored version, which is good indeed for the article, but not a striking enough graphic for a FP. Also, I think the secondary current should go outwards - looks a bit funny with the arrow pointing inwards... --Janke | Talk 21:00, 31 December 2005 (UTC)
 * Conventionally, in a 'two-port network' as is shown here, current is defined as positive for flows into the device. But aesthetically, yes, it looks better pointing outwards (see pic #3), and this is also common for textbook descriptions of transformers. --BillC 11:59, 1 January 2006 (UTC)


 * Support - illustrates the article just perfectly, the lack of colour doesn't bother me - Adrian Pingstone 10:01, 31 December 2005 (UTC)
 * Comment. Alternative colour version Image:Transformer3d col.svg on right. --BillC 13:20, 31 December 2005 (UTC)
 * Comment. Looks a lot better. moderate support because it illustrates the article well. --vaeiou 19:55, 31 December 2005 (UTC)
 * I like the red and blue wiring a lot, but the yellow text is hard to read at thumbnail size. &mdash;Cryptic (talk) 02:35, 1 January 2006 (UTC)
 * Third version Image:Transformer3d col3.svg loaded on right, having coloured the core to steel-grey, reversed the arrow on the secondary current, and changed the flux and text to green. I'll let this be the final version I upload. --BillC 11:59, 1 January 2006 (UTC)
 * Strong Support the coloured version. It is nicer than the bw. --Vidarlo 12:39, 2 January 2006 (UTC)
 * I'll support this one. Thank you for your responsiveness.  (The text is still slightly unclear here, but not when resized to 400px, as in the article.) &mdash;Cryptic (talk) 22:57, 1 January 2006 (UTC)
 * Support: it's the best picture of a transformer I've ever seen, it's very clear and the last colored version is very nice. Alessio Damato 15:54, 2 January 2006 (UTC)


 * Support the third version. Diliff  | (Talk)   (Contribs) 01:14, 3 January 2006 (UTC)
 * Comment. Is the green line with arrow misleading as to the magnetic flux? The way it's drawn seems to suggest that there is a changing magnetic flux only in the metallic part, which is incorrect (it's everywhere). I know it's hard to illustrate it being everywhere, but one could be misled that flux is some kind of "stuff" that only "flows" along the transformer core. enochlau (talk) 11:14, 6 January 2006 (UTC)
 * The diagram shows an idealised transformer, that is one with no core or copper losses, and one in which primary and secondary windings have perfect mutual coupling. There is an article (and diagram) at leakage inductance, which illustrates the effect of imperfect coupling you refer to. --BillC 17:27, 6 January 2006 (UTC)


 * support diagrams (prefer 3rd version). It sounds odd, but it would be even better if you could provide a reference for the image Broken S 03:33, 9 January 2006 (UTC)
 * Now done (on 3rd version). --BillC 06:53, 9 January 2006 (UTC)
