In this video we look at a lightning diverter for electric fencing and explain how it protects your energiser from voltage spikes caused by lightning strikes.

Lightning protection is one of the most overlooked parts of electric fencing. Without it, a nearby strike can send massive voltage down the fence line and destroy the energiser. Installed correctly, a lightning diverter sends that excess voltage safely to earth instead.

We also explain the role of correct earthing, why a super earth kit matters, and how to adjust the diverter so it activates only when dangerous voltage spikes occur.

This video will be useful for:

• Farmers running electric fencing systems
• Livestock producers using energisers for cattle, sheep or goats
• Contractors installing rural fencing
• Property owners wanting to protect their fence investment

Electric fences are incredibly reliable systems — but only if the earthing system and lightning protection are installed correctly.

If you run electric fencing, this is one component you shouldn’t ignore.
