Talk:Tap (transformer)

From Wikipedia, the free encyclopedia

I created this article unaware there was already an article Tap changer. Clearly both are covering much of the same material. If consensus agrees with the merger, I don't mind doing the legwork, including providing citations for the unsourced material. BillC 21:05, 17 January 2006 (UTC)

[edit] Animation speed

Has the animation been slowed down? It looks painfully slow to me now-- unless its my computer!--Light current 22:09, 27 February 2006 (UTC)

I added two extra intermediate frames to make the animation less jerky. But at the same time I reduced the pause time by about 20% for the frames with the rotating arm to compensate. On my computer, it's taking about 2 seconds for the arm to swing across from one side to the other. How long is it taking on yours? BillC 00:59, 28 February 2006 (UTC)

About 2 seconds!. It seems to have speeded up now and its OK!--Light current 01:06, 28 February 2006 (UTC)

[edit] Explanations for various terms used

I was looking forward to reading this article, but for me (with light/moderate electronics training) some of the terms were confusing. For example:

  • What does it mean to "buck" the voltage?
  • What is a star point?
  • What is a delta-connected winding?
  • The first paragraph (in the beginning) refers to tap points being on the high voltage side, but in the middle, talks about insulation requirements placing tap points on the low voltage end?
  • Is there a difference between a certain "end" of the winding and a certain "side" of the winding?

After reading the article, I really don't know much more than I began with, because I knew few of the terms involved, and didn't understand the first paragarph. I'm sure this seems completely logical to the Wiki-electronic-engineers, but I would really appreciate it if someone could make it more readable to the average person. This could be done either by adding wikilinks or by explaning what the terms mean.

Sorry for my lack of education in this area. --ZZYZX 23:07, 28 April 2006 (UTC)

You asK:
  • What does it mean to "buck" the voltage. This means to reduce oppose the voltage
  • A star point is a common point to which the earthy (low voltage) end of each (usually three) winding is connected.
  • A delta connected winding is where the coils or windings are connected at the vertices of a triangle.
The tapping is done on the high voltage winding, but near to its low voltage (earthy) end.
Sorry if these points were not clear. We will address them.--Light current 23:15, 28 April 2006 (UTC)

OK, that does make sense. Also, I'm guessing that in this context, the "side" refers to the voltage (high or low), and the "end" refers to the physical end of the transformer. I would offer to make these changes to the article, but I'd be the first to admit that I might inadvertently decrease the technical accuracy as well. Anyway, thanks for explaining it to me. --ZZYZX 23:42, 28 April 2006 (UTC)

Have a go! If its wrong someone else will correct it so dont worry! :-)--Light current 23:46, 28 April 2006 (UTC)

[edit] questions in regards to solid state thyrister switching

would some one be able to elaborate on solid state thyrister switching and perhaps indicate with a schematic how this is done. It seems that this circuitry is getting a bit more commonplace in smaller applications and im sure the readers would like to know more.
