What if the horns are vertical (many are). In which direction does the arc then travel?-- Light current 02:03, 21 March 2006 (UTC)
Examples of vertical arcing horns:
Yeah those look like proper horns to me!-- Light current 03:49, 21 March 2006 (UTC)
The first desc. sounds like a Jacobs ladder system reling on the bouyancy of the hot gases! OK. The horns Im thinking of are simple spark gaps mounted vertically or at an angle of say 45 deg on 11kV or 33 kV to LV transformers etc as per pic on electrical engineering page. In these cases, I think you must be correct in saying that some other device must interrupt the arc. However, for transient overvoltages only, would the arc not self extinguish at the zero crossing of the wave form? (maybe). When you say follow thro- do you mean power freq follow thro?-- Light current 03:37, 21 March 2006 (UTC)
Yes this of course makes sense! I had my brain in neutral when asking that question!-- Light current 07:07, 21 March 2006 (UTC)
This last link is not a bad picture of horns. Can we include it in the article (ie is it free of copyright?)-- Light current 03:37, 21 March 2006 (UTC)
I was just looking for an example picture to answer your question. Unfortunately, I don't own the copyright for this image... Bert 05:43, 21 March 2006 (UTC)
Anyone got a nice pic of arcing horns?-- Light current 02:19, 21 March 2006 (UTC)
