Pole-mounted transformers
Is it the case that pole-mount transformers are called substations in the US? In this country a substation is on the ground - it's just called a transformer if it's on a pole. --Ali@gwc.org.uk 00:17, 14 Nov 2004 (UTC)


 * The photograph is of a pole-mounted "substation" in Sydney, Australia. In my experience (Scotland, South Africa and New Zealand), the  substation is generally the distribution point from which the 11kV reticulation (SA) or distribution (UK and NZ) feeders emanate.  I would agree that a pole-mounted transformer is, strictly speaking, a substation but would generally be called a "pole-mounted transformer".  Similarly, a pad mounted transformer in an urban area fed from a reticulation or distribution feeder is a substation but is often described as a "mini-sub".  I can't answer your question about the US.  I would be inclined to accept any step down or step up installation as a substation notwithstanding convention in specific countries.Tiles 03:55, 14 Nov 2004 (UTC)


 * A pole-mounted transformer is never called a substation in my experience. "Substation" implies one or more feeders and one or more branch circuits, along with switchgear. A pole-mounted transformer in North American practice would usually serve only one building.  Although some may be inclined to accept any voltage transformation point as a substation, this is at variance with industry practice as I  understand it.   I have some pictures of substations which I think are more typical of the type. --Wtshymanski 00:12, 16 Dec 2004 (UTC)

Design and protection systems
I have started a section on the design of substations with relation to protection. I attended year aago a lecture by a high voltage substation expert whose specaility was protection syatems. Sadly I do not have references to many of the things which he talked out.

Does anyone know about events such as the Luton flashover, it was a serious flashover at the switching station at Luton (England) which caused a total failure of the high voltage system of the UK. It was a event many years ago which caused a change in the design of large substations. If you know about it please contact me via my talk page.Cadmium 11:59, 1 January 2006 (UTC)

Request
Hi!

Does anyone have reference information for the text on EE35T?

"Overview of substation design and layout (EE35T)"

Are there any design guides availble on protection of substation components ?

Thanks, Danish power engineer —The preceding unsigned comment was added by 80.196.96.35 (talk • contribs).
 * The U.S. Department of Agriculture has a department responsible for rural electrification. They publish detail design manuals on the Web for both substation design and overhead transmission lines. While these are only based on U.S. practice and rules, and have almost no theory component at all, going over these publications would be a good introduction to substation and transmission design. --Wtshymanski 21:13, 27 June 2007 (UTC)

Feeders
The "Feeders" link under the Distribution substation leads to a page about the Welch rock group "feeder" as opposed a component of an electrical distribution system.

I am not currently aware of what a feeder is, otherwise I'd write the article about it. Gord.Duff _at_ bchydro.com —Preceding unsigned comment added by 142.52.81.12 (talk) 16:13, 18 September 2007 (UTC)

Request
I would love to see information on the emittance levels of power sub stations. A formula perhaps. I know it degrades logarithmicly but not how to calculate the amount from the type of station.

I noticed there are no health related sections in this article. Would someone in the know add something with the word health related to sub stations? Then perhaps a link to the article on EMR.

Perhaps we could also add info about the art installation of flourescent bulbs that were auto powered by the EMR from an especially large sub station.

Thanks.

Request to merge Electricity Substations
The newly created (1 September 2008) article Electricity Substations should be merged into this article. It contains some UK-specific topics that are missing from this article. Truthanado (talk) 00:23, 1 September 2008 (UTC)
 * After a quick analysis, it is easier to just do the merge than to wait for discussion to complete. Speedy and bold merge completed. Truthanado (talk) 00:31, 1 September 2008 (UTC)
 * It is a pretty non-controversial thing to do - parallel articles, with the newer one created by someone who didn't check the spelling. As long as you keep the older one as the base you shouldn't have any issues. Wongm (talk) 03:51, 1 September 2008 (UTC)

Naming of Substations
How common is it in North America to name substations in honor of engineers and other people. Please expand this section! —Preceding unsigned comment added by 91.46.242.247 (talk) 16:47, 22 January 2010 (UTC)

It's more common to name substations after the area they are located in. However, it is up to the individual company what the station is named after though.173.219.132.98 (talk) 03:35, 3 September 2012 (UTC)

General comments
Cblambert (talk) 01:27, 16 February 2012 (UTC)

There are two distinct ground potential rise hazard issues:
 * Step potential hazard
 * Touch potential hazard.

Present wording misleadingly mixes up the two issues.

There are huge safety issues associated with substations including in terms of arc flashing hazard.

The section 'Stations with change of current type' is awkward at best. How about, using more mainsteam Power Electronics parlance, 'Converter Substation' instead? Which might lead to mention of term FACT, etc..

Any self-respecting article should include at least one reference to each of the following organizations:
 * CIGRE
 * EPRI
 * IEEE Power Engineering Society.

Would be nice to have at least one mention of the term 'SF6'.

What about differentiating low profile from high profile substation?

What about History section including in terms of evolution from DC into AC?

No mention of the term 'outage'?

96.52.198.210 (talk) 07:39, 16 February 2012 (UTC)In regard to step, touch potential hazard, etc. much better for article to have citation to IEEE Standard 80 “IEEE Guide for Safety in AC Substation Grounding” instead of to IEEE Green Book.

Cblambert (talk) 18:05, 16 February 2012 (UTC)There is also 'Indoor and Outdoor Substations - Overview' presentation on Slideshare at http://slidesha.re/yQDsjD that points to eventual LinkedIn link. Excellent material.
 * Well, here's a start at expanding with some of the above items. It's still light on footnotes. The USDA manual is 760 pages and doesn't exhaust the topic at all, so there could be much more written. One could write as much again on the economics of substations, for example. --Wtshymanski (talk) 15:55, 24 July 2012 (UTC)
