Understanding Lightning Diverters and Their Importance for Electric Fences

Lightning protection isn’t optional for electric fence systems—it’s essential insurance for your investment. Understanding how diverters work helps you choose the right protection level for your setup.

What Are Lightning Diverters

Lightning diverters redirect electrical surges away from your fence system during storms. They act as safety valves that open when voltage spikes exceed safe levels for your energizer.

These devices connect between your fence line and ground system. When lightning strikes nearby, the diverter channels excess electricity safely into the earth instead of through your expensive equipment.

Why Electric Fences Need Lightning Protection

Unprotected electric fences face costly damage from both direct strikes and nearby lightning activity. A single storm can destroy energizers, controllers, and connected monitoring equipment worth hundreds of dollars.

Lightning protection prevents system failures that leave livestock vulnerable. Without working fences, animals can escape or predators can enter your property during extended repair periods.

How Lightning Diverters Work

Lightning diverters contain gas-filled tubes or spark gaps that remain closed during normal operation. When voltage spikes from lightning exceed the diverter’s threshold, these components open to create a path to ground.

The diverter automatically resets after the surge passes through. This allows your fence system to resume normal operation immediately without requiring manual intervention or component replacement.
