I searched in the fencing forum and was surprised to not find any results for lightning suppression. Let's build a thread full of helpful information to have for us and future visitors to Permies.

I'm getting ready to install some electric fence on my farm, the moveable kind with step-in posts and reels of electric poly wire on reels so I can do rotational & mob grazing and easily change configurations. I want to install some lightning suppressors to divert lightning strike energy to ground instead of back to my fence energizer. There are several options out there, from very simple and reusable choke coils that operate on electric principals, to simple but one-time use lightning suppression, to fancier gadgets that cost 5 to 10 times as much as the most simple kind.

Who here on permies uses lightning suppressors on their electric fence, what kind do you use, have you had them work and save your equipment, and what do you like or dislike about them?

Hmmm... if only the problem was the solution and you could harvest that electricity! (Sorry, I just couldn't resist!)

We do use electric fencing on the outside of our shelters, but lightning is so rare here we haven't been concerned. Hopefully someone else will speak up with some real-world solutions.

The definitive (and legal!) standard for lightning protection is NFPA 780.

Try googling "lightning arrester for electric fence"  One manufacterer is Wellcraft and an example
of a hookup from their web site is below.

Can you smell this for me? I think this tiny ad smells like blueberry pie!
