Talk:Surge protector

From Wikipedia, the free encyclopedia

1 h-n, h-g, and n-g
2 iron poor vs. iron core

[edit] h-n, h-g, and n-g

I have a surge protector and it says it protects the h-n, h-g, and n-g lines. Any idea what it is telling me? It is for 3 prong US 120 V surge protector. Jrincayc 18:07, 23 May 2004 (UTC)

That probably means it has three MOV's, one each from hot:neutral, hot:ground, and neutral:ground. A spike on any of the three will cause the MOV's to short the spike out. --ssd 03:22, 29 May 2004 (UTC)

[edit] iron poor vs. iron core

Nearly all transformers are iron core. (Some are air core.) The article should say iron poor, meaning that the core has less iron in it than necessary to transmit the full current. Please don't confuse these and change it back. --ssd 18:28, 18 December 2005 (UTC)

[edit] external links wanted

I would like to see other websites apart from howstuffworks for this article. Anyone taking the bait? I would ask StuRat but I thought it would be better to post it here. -- Kushal one 17:43, 12 April 2006 (UTC).

[edit] MOVs do degrade

The page on MOVs (metal oxide varistors) says that they degrade over time. Also, in my personal experience and from the reports of many others, they do fail after time. The way companies get around paying up is to make it really hard to claim the insurance. For example, you need to prove that the damage was done by a power surge, which can be very hard if there are no obvious burn marks. Even the, can you prove it was the surge protector that failed? They also rely on most people not bothering to claim anyway, similar to rebate coupons.

Can you prove it? Because if so, it could be included in the article. 205.157.110.11 01:21, 22 February 2007 (UTC)

I gather that's an unintended pun :) --68.85.99.144 18:08, 4 November 2007 (UTC)

[edit] Picture

The surge protector pictured is obviously not American. Where is it from and should that be noted in the caption? PrometheusX303 21:03, 5 July 2006 (UTC)

It's a CEE 7/4 standard plug. See the Schuko article. I don't think this needs to be mentioned; its proves the point and is possibly a more internationally recognised format than the American style. ―AdamMillerchip 05:40, 15 December 2006 (UTC)

[edit] Surge arrester

Please see the original schematic from SchneiderElectric: http://d.interbild.net/vstoykov/tmp/shemi/surge_arrester_merlin_gerin.png and my modified verion: http://d.interbild.net/vstoykov/tmp/shemi/surge_arrester_merlin_gerin_MODIFIED.png (The blue line is the mechanical connection between circuit breakers!)

Where i may found free pictures of 1P circuit breakers and surge arresters to draw a free picture? --Valentin Stoykov, 09 October 2006

[edit] Silistor, what kind of arrestor is this?

In Japan, they commonly use a "silistor" in these kind of arresting situations, primarily in DC circuits, one leg of the silistor on the negative DC side and one leg on the actuated side, which is + DC. It does not appear that there is a polarity to the device. What is a silistor and how does it work and are they available in the US? 68.84.76.193 15:02, 8 November 2007 (UTC)

Apparently, a Silistor is a silicon-based PTC thermistor. It's more of a temperature-sensing device than an abrupt-cutoff protection one, so I'm not sure how it would work. Can you clarify? Reference: http://homepage.hik.se/staff/tkuwl/Measure_Sensors/My_Book_Temp_Whole.pdf

If it's simply connected across the supply lines, it could be a Silicon avalanche diode, a.k.a. transorb, under an unfamiliar name. A part number would answer the question more definitively. 71.41.210.146 (talk) 05:33, 8 March 2008 (UTC)

[edit] External links

I just found three external links in the article, apart from the open directory... and I removed all of them. Two were advertising for specific brands of protector, and the third link mentioned that it contains "numerous technical errors".

Does anyone here have the technical knowledge to verify that? I don't, unfortunately, and if the article is accurate it should go back in (and I apologise in advance for removing it)!

This is the link (as I found it in the artcle): HowStuffWorks: How Surge Protectors Work - This source contains numerous technical errors.
