What is an electric palisade fence made of?
Electrified palisade fences are usually made from painted mild steel, galvanized steel, stainless steel or aluminium. Typically the fences are 2.4 metres (7 ft 10 in) and typically send high voltage electric pulses through the palisade at a frequency of 1 Hz (one pulse per second).
How does an electric fence work?
Electric fences are designed to complete an electrical circuit when touched by an animal. A component called a power energizer converts power into a brief high voltage pulse. One terminal of the power energizer releases an electrical pulse along a connected bare wire about once per second. Another terminal is connected to a metal rod implanted in the earth, called a ground or earth rod. An animal touching both the wire and the earth during a pulse will complete an electrical circuit and will conduct the pulse, causing an electric shock. The effects of the shock depend upon the voltage, the energy of the pulse, the degree of contact between the recipient and the fence and ground and the route of the current through the body; it can range from barely noticeable to uncomfortable, painful or even lethal.
How long can you leave electric fencing in place?
With temporary electric fencing, a large area can be fenced off in a short period. Temporary fencing that is intended to be left in place for several weeks or months may be given additional support by the use of steel T posts (which are quickly driven in with hand tools and unearthed with relative ease, using a leverage device), to help keep the fence upright, particularly at corners. Livestock owners using rotational grazing in set patterns that are similar from one year to the next may permanently drive a few permanent wooden fence posts in strategic locations.
How to strengthen a fence?
Conventional agricultural fencing of any type may be strengthened by the addition of a single electric line mounted on insulators attached to the top or front of the fence. A similar wire mounted close to the ground may be used to prevent pigs from excavating beneath other fencing. Substandard conventional fencing can also be made temporarily usable until proper repairs are made by the addition of a single electric line set on a "stand-off" insulator.
Why are electric fences used?
Electric fences are occasionally employed to discourage suicide attempts on tall structures, and to reduce the incidence of graffiti and other petty crime .
What is the best wire for electric fencing?
Smooth steel wire is the material most often used for electric fences, ranging from a fine thin wire used as a single line to thicker, high-tensile (HT) wire. Less often, woven wire or barbed wire fences can be electrified, though such practices create a more hazardous fence, particularly if a person or animal becomes caught by the fencing material (electrified barbed wire is unlawful in some areas). Synthetic webbing and rope-like fencing materials woven with fine conducting wires (usually of stainless steel) have become available over the last 15 to 20 years, and are particularly useful for areas requiring additional visibility or as temporary fencing.
What is an electric fence?
An electric fence is a barrier that uses electric shocks to deter animals and people from crossing a boundary. The voltage of the shock may have effects ranging from discomfort to death.

How to check if a fence is properly grounded?
Once the fence is installed you should check to see if the fence is properly grounded. This is done by ‘grounding’ out the fence with a metal bar and than checking the ground rods with a volt meter. If the reading on the volt meter is higher than 200 volts you need more ground rods. There should be no volt reading on the meter with a properly grounded fence.
How high should a fence be for a one wire paddock?
Braces are the backbone of any good fence. For a one wire paddock division a lighter brace can be used. Ensure the horizontal brace is 2.5 times the height of the vertical brace post. There are many options to build braces; most critical is to have corner posts (4 to 5") at least at 3.5 feet in the ground.
What is a high tensile wire fence?

Should you energize the fence?
A common mistake is not electrifying it. Electric fence is a pain barrier, not a physical barrier. Animals conclude the fence itself is painful—and then avoid it.
How does an energizer work?
The energizer pushes an electric pulse through its “+” terminal to the fence. The pulse travels through the conductors and pressurizes the fence with excess electrons. That pressure is measured in volts. When an animal touches the fence, excess electrons enter it and travel through the animal to the soil.
How many volts does a fence energizer send?
Most modern fence energizers send very brief (less than 3/10,000 of a second in duration), high-voltage pulses (usually 2,000–6,000 volts) of electrons down the conductor every 1–2 seconds. Though powerful enough to deter animals and poultry, pulses this brief and this infrequent almost never pose a fire risk when the conductor is near combustible material. There simply isn’t enough “on” time for heat to build and allow ignition to occur.
How does a negative ground terminal work?
The negative ground terminal absorbs any excess pulse energy back into the energizer.
How does an electric fence work?
The positive fence terminal is extended by attaching conductive wires or electro-plastic cables. The negative ground terminal is extended by driving metal stakes or ground rods into the soil. (Soil moisture is a good conductor.)
Why is the length of a fence important?
Total length of fence: This is actually of minimal importance. Why? Because even small units will energize long fences and stop animals— if there are no leaks of energy to the soil via weeds or poor quality insulators.
What happens when an animal touches a fence?
When an animal touches the fence, excess electrons enter it and travel through the animal to the soil.
