| HOW AN ELECTRIC
FENCE WORKS
An ELECTRIC FENCE works
by "educating" your animals so that they learn to associate
touching the fence with receiving an unpleasant shock. This is the same
principle as barbed wire, but it presents a much more powerful deterrent
with very little danger of physical damage to your stock.
Electric fences are being used successfully
to control many kinds of animals, both domestic and feral.
The source of the shock is an electric
fence energiser. The energiser provides regular pulses of electricity
to your fence. These intermittent high voltage pulses flow from the energiser,
along a connection cable to the fence, and then along the length of the
fence. The "live" wires of your fence should not come into contact
with fence posts or corner posts, and this is achieved by the use of suitable
insulators.
When an animal comes into contact
with the fence, it becomes part of an electrical circuit between the output
terminals of your energiser. The strength of the shock the animal receives
depends upon the power available from the energiser, and the total resistance
of the circuit. |
