How an electric fence works?
Electric fence is a psychological barrier that keeps animals in and wild animals and predators out. A pulse of electric current is sent along the fence wire, about one pulse per second, from an energizer which is grounded. When the animal touches the fence, it completes the circuit between the fence and the ground and receives a short, sharp but safe shock. The shock is sufficiently memorable that the animal never forgets.
Because it is a psychological barrier, it does not require great physical strength. However, it must be well designed and constructed to absorb some pressure from animals, snow and wind. The energizer must have enough power for the length of the fence and for the animals being controlled.
