Lightning Protection: Reliable Safety for Energizers and Buildings

Protect your equipment from thunderstorms. Find reliable lightning protection devices for your electric fence here and save your farm from overvoltage.

Lightning Protection for Electric Fences: Safety Against Overvoltage

A thunderstorm can quickly become a danger to your electric fence and the energizer. If lightning strikes the fence, the enormous energy seeks the path of least resistance – and that often leads directly via the connection cable into the energizer. A lightning protection for the electric fence (also called a lightning diverter) prevents the worst. It is installed between the fence and the unit and routes the dangerous overvoltage directly into the ground. In this way, you not only protect your expensive energizer from destruction, but with mains-operated devices, you also prevent life-threatening building fires in the stable or farm.

Legal Requirements and Insurance Cover

The installation of a lightning protection device is not just a recommendation, but in many cases a requirement. According to regulations, mains energizers (230 V) located inside a building must be equipped with external lightning protection. If this is missing, you risk losing your insurance cover in the event of a fire.

How it Works and Easy Installation

Lightning protection usually consists of a spark gap. While the normal herding voltage can flow to the fence without any problems, lightning jumps the spark gap due to its extremely high voltage and is safely diverted via a grounding rod. Installation is simple: the lightning protection is mounted outside on a non-combustible wall or post and connected to the fence, the device, and the ground.

Frequently Asked Questions about Lightning Protection

Do I also need lightning protection for battery devices (12V / 9V)?
Lightning protection is not legally required for mobile battery or accumulator devices on the open pasture. However, to protect the device from an expensive total loss due to a lightning strike, retrofitting an inexpensive lightning diverter is still highly recommended.

Where exactly must the lightning protection be mounted?
It must always be installed outside buildings, preferably on a fireproof wall or a separate wooden post, before the fence supply cable is led inside the building to the mains unit.

Does the lightning protection need its own grounding?
No, not necessarily a completely separate one, but it must be connected to the grounding system of the energizer. Ensure that the grounding is deep enough and adequately dimensioned in dry soils so that the lightning strike can drain away reliably.

Reliable Lightning Diverters for Electric Fences

A lightning strike into the fence system can have devastating consequences. To prevent the millions of volts of lightning from shooting into your energizer and destroying it, a lightning protection device is essential. Especially with 230-volt mains energizers installed in the stable or barn, the external lightning protection prevents the lightning from entering the house's power grid and causing fires there.

In our range, you will find standard-compliant lightning protection devices that are easy to retrofit. They safely divert the overvoltage into the ground via a spark gap. Equip your fence system now, fulfill the requirements of your fire insurance, and sleep peacefully even during strong thunderstorms.
