Talk:Electricity distribution

Help required with formatting !! The text needs wrapping. Tiles
It failed to wrap because the line began with a blank space. Deletion of that one blank space is all that was needed to fix the problem. 131.183.81.100 23:20 Apr 18, 2003 (UTC)

Re-added some U.S. info that had been deleted, in the interest of specificity. Making the article international is great, but I think we should cover the various distribution systems separately rather than have an overgeneral article that says too little.
- It is hard to get a balance, but the more detail is added the more explanation is required. For instance, you refer to "grounded" and "wye", I would use "earthed" and "star" for the same concepts. Should readers come to wikipedia for technical detail or a general overview? The article could be expanded to include sections on the distribution systems of different countries if contributors make the effort. Your changes improve the article and create an opportunity to expand and improve it further, if others take up the challenge. Tiles 20:09, 1 Oct 2003 (UTC)
I have removed the following: "The skin effect is the tendency of a high-frequency electric current to distribute itself in a conductor so that the current density near the surface of the conductor is greater than that at its core. This means DC power cables can be thinner than AC power cables and still carry the same electrical power. However, transforming DC to high voltages is a difficult process and this offsets the gains from material savings. Use of high voltage DC lines is only now becoming economically interesting for very large distances and with the increased availability of high-temperature superconductors."
It is not relevant to the article, which is about electricity distribution, not transmission, and it contains errors. See high voltage DC for an explanation of the advantages and disadvantages of HVDC and note that it has been used for long distance transmission since 1954. At power system frequencies skin effect is negligible. Tiles 20:09, 1 Oct 2003 (UTC)
Several things are unexplained or unlinked. What do these things mean? (Should they have articles?)
- 2200 volts to ground
- 2200 volts corner-grounded delta
- 2400Y/4160 three-phase systems
- 220Y/380
- earthed/grounded (with respect to distribution)
- wye/star
can anyone help? Rmhermen 20:30, Oct 1, 2003 (UTC)
I would like to know at least the basics of how power is supplied to vastly varying loads, how it is switched from area to area or whatever depending on power needs, how many different generators supply many different loads over the same wires... Maybe that should belong in a different article? - Omegatron 16:40, Jun 21, 2004 (UTC)
"distribution systems were single phase and used a voltage of 2200 volts corner-grounded delta."
this seems like a contrdiction to me... perhaps someone more familiar with US systems could fix it. --Ali@gwc.org.uk 14:33, 6 Nov 2004 (UTC)
