DIY- How to Build a DIY Lightning Diverter for Electric Fences
Nope RopeShare
Lightning strikes can wreak havoc on your electric fence, especially damaging the energizer, the heart of your system. While you could buy a commercial lightning diverter, building your own can be a cost-effective and fun solution. This guide will walk you through the steps to create a DIY lightning diverter with simple materials, keeping your fence and energizer safer from lightning surges.
Materials Needed:
- Metal conducting rod (galvanized steel or copper)
- Insulated wire (heavy-duty for outdoor use)
- Spark gap setup (two conductive metal plates or pieces)
- Ground rod (for lightning diversion)
- Screws and fasteners
- Weatherproof housing (optional but recommended for durability)
Step-by-Step Instructions:
1. Install a Spark Gap:
- What’s a Spark Gap?: A spark gap is the space between two conductive objects that allows high-voltage electricity (like a lightning strike) to jump from the fence to the ground.
- Set It Up: Place two conductive metal plates about 1/8 inch apart. One plate connects to the live wire of your fence, while the other connects to a ground rod. The spark will jump between the two plates when a lightning strike hits.
2. Connect the Diverter to the Fence:
- Use insulated wire to attach one plate of the spark gap to the live wire on your electric fence.
- Ensure the connection is tight and secure using screws or fasteners.
3. Secure the Diverter to a Ground Rod:
- Drive a ground rod (6 to 8 feet long) into the ground near the fence.
- Connect the second plate of the spark gap to the ground rod using insulated wire.
- This creates a direct pathway for the lightning to safely flow into the ground, bypassing your energizer.
4. Enclose the Diverter in Weatherproof Housing (Optional):
- Protect the spark gap and wires from the elements by enclosing them in a weatherproof box. This step is optional but will extend the life of your DIY diverter.
Building a DIY lightning diverter is a simple and budget-friendly project that can save you from expensive fence repairs. By following this guide, you’ll be better protected from unexpected lightning surges and help preserve the life of your energizer.
