Snow, ice and frozen soil are insulators. In winter,
the flow of electricity is blocked by snow and ice
and no shock occurs.
A shock occurs when electricity passes through
the animal into the ground and back to the ener-
giser from the earthing rods.
= SHOCK
= EARTH
5. How does an electric fence work?
When an animal touches the electric fence, electrical current of an energiser fence output impulse passes from the
fence wire to ground through the animal, and back to the energiser through earthing rods and the earth conductor,
giving the animal a shock on the way. Adequate earthing is essential for the electric fence to function properly.
In summer and in good fencing conditions, earth conducts electricity well. If the electrical path between the animal
and the ground is interrupted for some reason, the animal will not receive a shock, even if the energiser functions
properly.
Snow, ice and frozen soil are good insulators. In winter, electricity cannot pass from the animal’s feet into the
ground through the snow and ice, and the animal does not receive a shock when it touches the fence. Thus, even if
the energiser functions flawlessly, the flow of electricity is interrupted by the insulating snow and ice.
A functional winter fence is implemented by providing a separate return path for electricity in the form of,
for example, a) two-wire fence, or b) winter fence tape.
The flow of electricity between the animal and the ground can also be interrupted in summer,
in very dry conditions or on rocky terrain. Under such circumstances, a fence built in
compliance with the winter fencing instructions is a functional solution.
You can find the Winter Fencing Guide and other instructions on
fencing in the Manuals and Guides section of Olli website.
Protection against splashing water is effective only if the energiser is installed in the vertical position. Do not install
the fence energiser upside down. Do not overtighten the mounting screws. The warranty does not cover moisture
damage resulting from improper installation.
If the fence energiser is damaged, remove it from use and have it repaired by a qualified Olli Service Partner or
recycle it in accordance with local regulations for electronic waste.
For safe passage through an electric fence, provide it with a gate. A fence requires regular monitoring. Animals
trapped in the fence wires may be in danger of life.
Spring gates are not recommended for horse fences due to the risk of tail hair entanglement.
Note that animals must be trained to remember the shock from the fence. Otherwise they will not respect the
electric fence.
