Lightning can cause serious damage to your energiser. When lightning strikes close to (or directly on) an electric fence, it causes a massive surge in voltage which flows back to your energiser to find the quickest path to earth.
The only fail safe method to avoid damage occurring to your energiser during an electrical storm is to disconnect it from the fence line and from the mains power supply. For safety reasons, never disconnect the energiser during an electrical storm.
A practical alternative to this is to install a Stafix Lightning Diverter Kit. The kit contains all the components needed including a Choke. The Choke creates a blocking effect for the extremely high voltages caused by lightning. The voltage is blocked by the choke and diverted across the arrestor to earth. The earth system on the lightning arrestor must be as good as, or better than, the earth system for the energiser.
For the best possible protection install the Lightning Diverter as close as possible to the energiser. This can either be in the leadout or in the first section of fence line. Full instructions are supplied with each kit but the diagram below depicts a typical setup.
