Lightning arrestors.

[JillSwift]

Someone mentioned worrying about thier surge protector being functional as a lightning storm rolled in and I got to wondering:

I have a Delta CA302 R in my circuit breaker panel, which I think may have saved my bacon on a couple of occasions. Because it's deigned with lighting in mind, and doesn't protect against smaller surges, I also have individual surge protection on my delicate electronic stuff.

Does anyone else use lighting arrestors?

We use one on our outside wireless antenna.

I don't have a lightning arrestor, since the power lines are underground. However, I have little surge suppressors (MOVs) on each power bar and one or two of them have blown up over the years - committing suicide to protect the stuff connected to it.

No.

I do own an APC surge protector (cheap one) which helps prevent the system from going down when lightning causes short blackouts (a few seconds), thereby not losing any data and prevents file corruption of the filesystems.

I don't use anything. I don't think...

I think our power lines are underground but I wouldn't mind having a surge protector just in case. And besides, I live in THE LIGHTNING CAPITAL OF THE WORLD DX (aka, the sunshine state ._.)

Don't really know what those are. Some kind of grounding device?

In essence, yes. They shunt voltage to ground during a lightning strike and through their capacitance they also limit changes in voltage to the outlet during the strike.

Heh heh, "lightning freedom" - well done.

I've never heard of one.
