Lightning Strikes a Computer strikes a...

Here's a recent item:

http://seattlepi.nwsource.com/national/apus_story.asp?category=1110&slug=Lightning%20Strike

The story reminds me that I still have computers protected by 12-year-old Zero-Surge surge protection devices, which are still doing their job.  The company is still in business, but I never hear much about them, or any other surge protectors, for that matter.

Is there much concern out there about how best to keep your computers from frying in a storm?  What do you use?

I've been using my "EPD EC-II" surge protector for the past 20 years, non-stop, and even the LED's which have been glowing 24/7 are still working fine.

Geeze. Apparently God did strike him down for masturbating.

"The story reminds me that I still have computers protected by 12-year-old Zero-Surge surge protection devices, which are still doing their job"

No they're not, unless "their job" is to be an extension cord. The surge protection circuitry most likely burned out years ago.

However, that's not going to protect you from a lightning strike anyway - the thing most likely to protect you is tying a knot in your power cables. The inductance of that one loop will hopefully arrest most of the surge. The downside is that it will also most likely immediately burst into flames.

HOWEVER, a friend of mine said he's done the physics on lightning traveling along a power cord and the knot thing won't work, since the surge will most likely ionize the insulator and bypass the loop. [shrug]

I pay off the Christian Coalition and pray as well on top.

No point taking chances.

Philo,

Actuallly, probably not.  Zero-Surge has one claim to fame: a patented circuit based on a huge inductance coil to stop surges cold (except, perhaps, for direct hits--though it's never been tested that way AFAIK).  At the risk of appearing to be a pimp, here's their explanation:

...And may they roast in Hell for aeons.

Stupid question - can anyone find mention of a warranty on their site? I can't (but I do have a tendency to miss something while staring straight at it)

There's a page saying that it's met the government's best certiication standard (1,000 surges of 6,000 volts, 3,000 amps).

Note that a lighting strike has travelled 1000s of feet through thin air, via a potential difference of 100,000,000 volts, with a current of 100,000 amps or more.

http://www.astrosurf.com/lombry/qsl-lightning-protection.htm makes interesting reading; the safest protection is to unplug devices; it also notes that, if all devices are protected, then it's the operator who is often the easiest path to ground.

I have the Zero Surge Warranty listed at my site: www.hlstores.com/site/614020/page/341090
