Talk:Switchgear

.......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.

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...

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?

Medium Voltage deleted

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]
