Is there anyway to prevent a ground line surge for flying your stuff in your house. Surge suppressor wont help

There was a near field lighting strike and it came in the ground line into my house and fryed lots of things. there was surge suppressors on all the stuff that got fried!!!! any ideas? All surge supressors will not help that type of surge!!! thanks again, 73

You should have good grounding rods at your service entrance. You can extend these around the perimeter of your house, all connected with a large copper wire. Also you can have a lightning arrestor installed in your service panel which is quite effective. Here's a decent writeup:

Reply:I can't think of anything that can protect you from that. Surge suppressors work by taking excess power TO ground. Same with lightening rods. And GFI protectors I think trip by sensing differences to ground also.





What you are talking about is lightening coming in THROUGH ground (as you realize).





But lightening is such high voltage it will jump switches and safeties, including surge devices, even breakers that are turned off. So I think there is no protection.





What you are talking about is a little new to even the scientists. They thought lightening dissipated in the ground. But I read of recent tests because they were still having some problems with lightening and underground wiring and they found that even underground lightening would seek out the power cables and travel along them.





I think you shouldn't worry about it happening again. Don't they say lightening doesn't strike twice in the same place? LOL.
Reply:USA There is no guaranteed protection from a very near or direct lightning strike. However, individual plug-in appliances (TVs, stereos, etc.) can be protected by multi-outlet surge protection devices. These devices are rated by how much energy they can safely interrupt - namely, how much electricity can they shut off before it blows out your tv. They are rated in joules. The higher the joules rating, the better the protection. The cheap ones are 1600 or 2000 joules, and provide next to no protection. Go for 20,000 or more joules to protect expensive equipment.





The best lightning protection system is a good ground system attached to ground rods, metal water pipe and building steel. A good system surge suppression system is a totally different concept, and needs to be designed by an electrical engineer.
Reply:If you own your home you can install or have installed GFI outlets. They are designed to stop ground surges. You can get more info and buy them at lowes, home depot or a hardware store. This is going to be a little bit expensive. However, it's cheaper than replacing all of your stuff.
