How Electric Fencing Works

An electric fence is a circuit. The current passes through the wire to the animal or long grass, then via the earth stakes in the earthing system, back to the unit.

Electric Fencing Components

• An Energiser to provide the current
• Fencing wire to conduct the current
• Insulators to insulate the wood or metal posts so the power does not drain to the ground
• An earth system that conducts the current back to the energiser
• An animal to receive the shock if it contacts the fence, thereby completing the circuit

The electric fencing offers many advantages over conventional fencing. Firstly, electric fencing is economical (50% less costs/ labour), in terms of material and work. You can install electric fencing yourself or get a contractor to do it for you. Electric fencing is also a psychological barrier. Your animals will avoid it after their first contact. Because of this, your electric fencing is very effective, and more safe than a fence that’s not electric. This means that the physical load on an electric fence is virtually zero. Result: Increased service life!
