Why Use Electric Fencing?
Electric fence systems are used to control a wide variety of animals. A typical electric fence is a psychological barrier that keeps domestic animals in and nuisance animals out, even over long distances.
High Tensile electric fence systems are very strong, cost-effective physical and psychological barriers for the control of animals.
How It works
How Electric Fence Systems Work
A typical electric fence is a psychological barrier in the sense that the animal will touch the electric fence and become “trained” not to go near it.
When an animal comes into contact with an electrically charged fence wire, it will feel a shock because the electric current will pass through the animal to earth (ground), thus completing the electrical circuit. If the animal and the ground terminal of the electric fence energiser are not sufficiently grounded, the path of electric current cannot be completed and the animal will not feel the shock.
The fence must be well-designed and constructed to absorb some pressure from animals, snow and wind. The fence's energiser must have enough power for the length of the fence and for the animals being controlled.
Since the earth itself makes up half of the electric fence circuit, it is very important to have a properly installed earth system. In areas where poor soil and poor earth conditions exist, a two-wire system can be used with one wire being live while the other wire acts as earth. This two-wire electric fence system is utilised when there are alternating “live” and earth wires installed.
Also, the electrically charged fence wire must always be properly installed and not be allowed to come into contact with shrubs, tall grass, and any other conductive objects on a continual basis. Otherwise, the electric charge from the fence wire will be lost to earth, thus reducing the power on the fence wire.
Regardless of what wiring system is utilised, earth stake(s) and their connection to the energiser's earth terminal must always be used.
