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


How Electric Fencing Works

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!
