Talk:Switchgear

Page contents not supported in other languages.

.......I removed the section entitled "Manufacturers" because it only contained one manufacturer of switchgear, and appeared as more of an ad, than a resource. A google search for "switchgear manufacturers" will yield a number of manufacturers and distributers.

Switchgear vs. Switchboard

[edit]

Perhaps someone smarter than me can point out the differences? Tara Zieminek (talk) 23:07, 13 March 2014 (UTC)[reply]

[edit]

I suggest to add this link in the category External links of switchgear definition. On this web page (without commercial advertising), we can find a switchgear definition and an access to a pdf file wich contents as topics : the basic functions of LV switchgear,the different types of switchgear,coordination between circuit breakers, principle of discrimination / selectivity,choice of breaker type and performances... basic functions of LV switchgear, different types of switchgear, coordination between circuit breakers, ... from Merlin Gerin web site --Jeblo 08:19, 5 June 2006 (UTC)[reply]

very useful; NOT VERY USEFULL!

Question - Where would motor control, particularly Motor Control Centers, low & medium voltage (LV-MCC, MV-MCC) belong? A reference from this article to others?

I added a separate MCC article (by separating out the "motor control center" section of the "motor controller" article). Find it here: Motor control center Tara Zieminek (talk) 23:10, 13 March 2014 (UTC)[reply]

Medium Voltage deleted

[edit]

I deleted the reference to medium voltage anonymously). As was noted here previously the IEC only defines High and Low (and extra low) voltage. The reason IEC doesn't have a definition of Medium voltage is that in different countries this phrase was, in the past, used to mean very different things - three phase 415V in some countries, 11kV distribution in others.

I remember this but don't have any references to hand so I can't do a Medium Voltage page today.Filceolaire 11:24, 23 August 2007 (UTC)[reply]

I have restored medium voltage and given the range of voltages to which this applies. IEC definitions seem to be inadequate. It is a well understood class of switchgear (see my reference, for example, also IEEE Standard 100 defines medium voltage for several different uses). Even the most European of IEC engineers could not possibly confuse a 500,000 V gas-insulated transmission circuit breaker with a 4160 Volt motor starter or a 415 volt disconnect. Do not delete references to medium voltage switchgear in this article. A Medium voltage page would only be a dictionary definition and not a useful encyclopedia article in its own right. --Wtshymanski 18:13, 24 August 2007 (UTC)[reply]
I support this, IEC is now introducing the term Medium voltage in the coming IEC 62271-1, it means higher than 1 kV and up to and including 52 kV. Dingy 04:11, 25 August 2007 (UTC)[reply]

Hatnotes re style and refs

[edit]

Not my field, but both style and cites seem adequate for a start-class article. Old warnings, maybe? Comments? --Pete Tillman (talk) 01:15, 22 September 2013 (UTC)[reply]

Interrupt fault currents

[edit]

The phrase "interrupt fault currents" gives the impression that is the only purpose of switchgear. Some circuit breakers, for example the Generator Circuit Breaker in a power plant, is designed to break the full-load current of the generator, still thousands of amps but not what you would call a fault current. Any comments?--Graham Proud (talk) 03:22, 28 May 2014 (UTC)[reply]

Hello fellow Wikipedians,

I have just added archive links to 2 external links on Switchgear. Please take a moment to review my edit. If necessary, add {{cbignore}} after the link to keep me from modifying it. Alternatively, you can add {{nobots|deny=InternetArchiveBot}} to keep me off the page altogether. I made the following changes:

When you have finished reviewing my changes, please set the checked parameter below to true to let others know.
