Talk:Delta-wye transformer

Untitled
Standard single-phase voltage in Europe is now 230 volts, see Mains power systems. Biscuittin 09:50, 30 May 2007 (UTC)


 * Not correct. European single-phase voltage is nominally 230 volts.  In individual territories, the voltage is what it has always been.  In mainland Europe, 220 volts.  In UK, 240 volts (with some pockets of resistance at 250 volts in the suburbs of large cities).  In each case the voltage conforms to the nominal European voltage of 230 volts ±10%. 109.145.21.107 (talk) 16:12, 30 January 2012 (UTC)

ridiculous un-searchable article name
What a stupid name for an article. How is anybody supposed to find this through direct searching? (How do I even type that goofy triangle shape?)

Is there really no direct english language name for this device? I am going to do some research and possibly move this to a more searchable article name. DMahalko (talk) 15:27, 16 May 2008 (UTC)


 * delta wye works for me. 170.119.0.39 (talk) 13:33, 6 April 2009


 * If you look back at the edit history, the previous name was "Δ-Y transformer" before I moved it to the current name "Delta-wye transformer". I would really like to know who would first try typing "Δ-Y" to get here.. DMahalko (talk) 04:02, 7 April 2009 (UTC)

Diagram is incorrect
The schematic shows a Star Delta Transformer. The solution is for the schematic to be flipped vertically. Perhaps for clarity, the primary and secondary windings should be labelled as such. — Preceding unsigned comment added by 155.143.168.204 (talk) 15:57, 18 November 2015 (UTC)

The diagram shows two connected ends of the star winding connected to neutral. The star windings should + to - all the way round the delta.202.124.120.18 (talk) 21:29, 22 December 2010 (UTC)


 * The center part is delta and its connected correctly, but the drawing is confusing. Cantaloupe2 (talk) 21:45, 23 December 2012 (UTC)


 * What do you find confusing? As for the connections, I had altered the drawing based on the IP's comments; so it should be correct. — Preceding unsigned comment added by Gargoyle888 (talk • contribs) 19:29, 12 January 2013 (UTC)


 * The actual hook-up is correct and this type wiring diagram maybe preferred by wire hook up technicians who may struggle to read schematics in general, but it's not as visually intuitive as something that show Y|∆ layout. Cantaloupe2 (talk) 21:07, 12 January 2013 (UTC)

Appropriate inclusion for chart
Phase-to-phase voltage (approximate. √3 ≈ 1.73 ) is a the mathematical relationship and expressing it as 1.73 is dumbs it down for those who can't figure out sqrt3. 100:173 gives a perspective in terms of percentage which as far as I know is an expression used worldwide.

Why should the table start at an arbitrary chosen voltage that happens to be used in NA? Why 120? if 347 is included... why not 452? how about 653, 812, 85 and an endless list numbers? Cantaloupe2 (talk) 21:14, 24 December 2012 (UTC)
 * Feel free to add more examples for the reader clarity. I don't like the format of this chart at all. It's too large in appearance. I think the examples are good but there are many more examples of transmission voltages. It needs to compacted into a small list or something more compact. Let me try to compact this and see how you like it. 174.118.142.187 (talk) 22:21, 6 January 2013 (UTC)
 * Is there a reason you're inserting made up number pairs that do not hold proper mathematical relationship? The concept of rounding is a generally accepted practice globally. You're pairing numbers like 600 to 347. If 600 is divided by root of 3, it is 346.4 therefore it rounds down. This article isn't about NA, so trade jargons that only work in your Incorporation of Municipality is nay way. Cantaloupe2 (talk) 22:54, 6 January 2013 (UTC)
