4.3.2 Install Lightning Diverters
Lightning will damage your energizer if
it strikes your power fence. Gallagher
energizers have internal lightning diverters
that give partial protection against small
strikes. Installing an Adjustable Lightning
Diverter (G6480) will give added protection
by providing a path for the lightning that
strikes the fence to be diverted to ground.
Otherwise disconnect the energizer
from the fence and power supply during
lightning storms.
Lightning always finds the easiest way to
earth. In areas where lightning is a problem
installing an earth system to include a
lightning diverter earth is essential.
Recent trials have shown that combining
the energizer earth and lightning diverter
earth not only improves the energizer
earthing but also protects it from lightning
damage. The minimum number of earth
stakes is three. See the recommended
earth installation below.
Using the diverter does not guarantee
complete protection. In bad lightning
areas, earthing the top fence wire helps
significantly.
Low protection against
lightning strike.
Medium protection against
lightning strike.
High protection against
lightning strike.
