three phase voltage

@Wtshymanski: Change [1] claims: "not true enough to be worth saying here" about the fact that three phase nominal voltages are by a factor of √3 larger than the corresponding single phase. I would say, that the difference between three phase voltages (phase to phase) and single phase (phase to neutral) is always sqrt(3), as this is a fact from geometry [2]. Basically the cosine of 30° is half of √3, and this ratio does not change whatever voltage level you choose. Therefore the relation between three phase voltage and corresponing single phase voltage is always √3 and obviously this is worth saying here at it is not known to everyone. "for instance, 480 V systems, 600 V systems" - I am not sure about these voltages but it seems (see IEC_60038) that 277 V / 480 V and 347 V / 600 V are the corresponding 1ph vs 3ph voltage pairs, thus the statement is perfectly right.

The point is that 277 V and 347 V are never distributed as single phase utilization voltages. It's excessive detail and off topic for this article. --Wtshymanski (talk) 19:35, 14 May 2020 (UTC)[reply]

I think it depends on what you mean by distributed. Yes they are never distributed single phase, for example on outdoor overhead lines. But they are commonly distributed within buildings. It seems that in (US) commercial buildings, 277VAC is common for lighting. There might be one phase distributed to each room from the breaker panel. It is, then, a common voltage for fluorescent, and other discharge lamp, ballasts. Now that electronic ballasts are more usual, there are many that will run on any voltage from 120VAC up to 277VAC. (Though not claiming that means it should be in the article.) Gah4 (talk) 20:33, 14 May 2020 (UTC)[reply]

The 3 phase vs single phase voltages in the table are definitely incorrect in many cases.

There may be other higher voltage 3 phase supplies in some cases, but in almost every case in the table, the 3 phase voltage should be √3 times higher than the single phase voltages and/or vice versa.

E.g. Antigua and Barbuda is stated to be 230 volts single phase and 380 volts 3 phase. Either the 2 phase voltage is incorrect or the 3 phase voltage is. 230 x √3 = 398 volts and 230/√3 = 219 volts. According to this the 3 phase voltage in Antigua and Barbuda is 400 volts. https://www.worldstandards.eu/electricity/three-phase-electric-power/ Lkingscott (talk) 10:02, 20 December 2022 (UTC)[reply]

I have updated the voltages according to various sources for cross checking, but primarily the 3 phase voltages according to https://www.worldstandards.eu/electricity/three-phase-electric-power/

In particular the line and phase voltages are more consistent now, however the following places have different voltages shown in different sources and the single and 3 phase voltages are inconsistent:

Cape Verde

Haiti

Honduras, some sources say 110 and others 120V

Lebanon, some sources say 220 some 230V for single phase, but 3 phase is 400V, so 230V is more consistent.

Mauritania, some sources say 220V 3 phase others 380V, which would be more consistent with the 220V single phase supplyLkingscott (talk) 11:49, 20 December 2022 (UTC)[reply]

Unreliable source #26

"Confirmed by looking at Aqualectric meter" is something like original research? Not a major editor so I'm not gonna actually go in and correct it, but like. Ellenor2000 (talk) 14:57, 9 October 2023 (UTC)[reply]

Please help me with... Hello!

I came across the data in Wikipedia, today, for which I believe is wrong. It's about electricity in Slovenia. There is a table that says it is 230V, but in fact it is 220v. It's here:

https://wiki.riteme.site/wiki/Mains_electricity_by_country

I don't know how to edit it, so I decided to just write here. Couldn't find any other possibility.

Thanks in advance for correcting that data.

Best regards, Alja Žehelj (from Slovenia) 89.233.115.214 (talk) 17:28, 14 March 2024 (UTC)[reply]

Three-phase voltage for Belgium and Japan

In the table section for Belgium, the three-phase table cell says 230/400 V. Although I can not verify, doesn't Belgium have similar systems like norway having both 230 V (three-phase without neutral) and 400 V (230 V/400 V star with neutral)? Although I don't think belgium commonly uses the IT grid, unlike norway. Now for japan, where is the source for the 415 V three-phase (either delta, or 240 V/415 V star) that is supposedly in use in Japan?

I'm new to the talk section, so I will do my best to follow guidelines on discussion boards. Additionally, I rarely edit wikipedia articles so I am not going to make edits yet. TheDIsco00010 (talk) 20:36, 30 May 2024 (UTC)[reply]

Saba and Sint Eustatius

Dear anonymous editor: Please stop reverting and find sources. The ones I have found did not agree with you:

For Saba 110V/60Hz [3]
For Sint Eustatius, a combination of 110V/220V [4]

These sources might be wrong, but you need to provide better ones in order to introduce these island into the table. Викидим (talk) 20:35, 2 July 2024 (UTC)[reply]
