1. [TowerTalk] Lightning Damage (score: 1): Author: "Bruce Carpenter" <Bruce.Carpenter@earthlink.net>; Date: Mon, 17 Aug 2009 15:20:13 -0400; Les I have read the message you posted on the lightning protection forum. First, we must recognize that no level of protection will totally protect electronic equipment from lightning damage. We can; /archives//html/Towertalk/2009-08/msg00326.html (13,025 bytes)
2. Re: [TowerTalk] Lightning Damage (score: 1): Author: jimlux <jimlux@earthlink.net>; Date: Tue, 18 Aug 2009 06:32:24 -0700; Better not to think of it as a transmission line, rather, a straight inductance. 8 feet is about 2-3 microhenries (in a straight line). If the full stroke current flows through it, the voltage can be; /archives//html/Towertalk/2009-08/msg00330.html (17,161 bytes)

Re: [TowerTalk] Lightning Damage (score: 1): Author: Michael Tope <W4EF@dellroy.com>; Date: Tue, 18 Aug 2009 08:13:23 -0700; Hi Jim, Shunt suppressors should terminate to ground (preferably at a SPG bulkhead) not another parallel conductor. BTW, I am not familiar with series suppressors (my own ignorance) other than the se; /archives//html/Towertalk/2009-08/msg00332.html (10,185 bytes)
4. Re: [TowerTalk] Lightning Damage (score: 1): Author: "Jim Brown" <jim@audiosystemsgroup.com>; Date: Tue, 18 Aug 2009 09:46:57 -0700; Series-mode suppressors have been developed that are quite effective on power line branch circuits. They work by storing the strike voltage in a very large inductor, then discharging it slowly once t; /archives//html/Towertalk/2009-08/msg00335.html (9,551 bytes)

Re: [TowerTalk] Lightning Damage (score: 1): Author: jimlux <jimlux@earthlink.net>; Date: Tue, 18 Aug 2009 10:36:51 -0700; One example would be a series L followed by a shunt C (yes.. a low pass filter).. In a typical transient, the real problem is the high peak voltage, not necessarily the actual energy in the transient; /archives//html/Towertalk/2009-08/msg00338.html (9,604 bytes)

Re: [TowerTalk] Lightning Damage (score: 1): Author: "Bruce Carpenter" <Bruce.Carpenter@earthlink.net>; Date: Tue, 18 Aug 2009 02:35:24 -0400; Jim Your are correct in all of your comments and I agree fully. I did not go to that level of detail as I was trying to keep my comments relatively simple. The reason I mentioned that non UL listed d; /archives//html/Towertalk/2009-08/msg00359.html (19,706 bytes)
