[edit] reasons for cascading failure

From the article: Under certain conditions, a network component shutting down can cause current fluctuations in neighboring segments of the network.

May someone explain the reason for such events more precisely? Thanks --Abdull 17:02, 21 July 2005 (UTC)

[edit] Third world countries

The article says: "In most third world countries, power cuts go unnoticed by most citizens of upscale means, as maintaining an uninterruptible power supply is often considered an essential facility of a home."

Let's rewrite this sentence. It uses weasel words like "most" and "often considered" as well as the poorly defined phrase "of upscale means". And how would we verify this claim? Tonyfaull (talk) 23:55, 17 January 2008 (UTC)

[edit] Suggestion

Power outages may also be caused by terrorism (attacking power plants or electricity pylons) in developing countries. The Shining Path movement was the first to copy this tactic from Mao Zedong.

is awkward, what's so special about being the first to copy something?

Power outages may also be caused by military or terrorist attacks (attacking power plants or electricity pylons) in developing countries. This tactic was used by Mao Zedong; the Shining Path movement was the first terrorist group to copy it.

might be a better way to say it. —Random832 14:56, 30 January 2008 (UTC)

Is there any reason why a search for "Power Outage" links to [1] and not [2] I mean this article would be alot more useful than one about Charmed Episodes and it's alot more relevant. If someone could correct this because I'm not sure how. Vergil 577 (talk) 10:15, 28 May 2008 (UTC)

[edit] Brownout

Do we have a citation that a brownout is a drop in voltage rather than current? My understanding (partly from National Grid (UK) reserve service) and from speaking to professionals from the electricity generating industry is that a brown out is the result of the frequency of the grid falling below normal operational levels (resulting in less available current), as opposed to the actual voltage dropping. I'm happy to be wrong, but I currently interpret the two articles to be contradictory. -- ratarsed (talk) 09:09, 2 October 2008 (UTC)

A redirect SAG reffer to this article (i mean Voltage sag). but here isn´t information about sag. --89.103.53.32 (talk) 15:35, 21 December 2008 (UTC)
