Electric Fencing

An electric fence is a form of Access Control. It is a barrier that uses electricity which would cause an electric shock when touched. It is a deterrent to animals and or people from crossing certain areas, like a boundary, or a place of danger.

It uses a voltage of shock to determine the “force” which would cause discomfort or death. There are standards in place to which the voltage is set.


Fence Energizers:
When the fence energizers first came around the fence energizers used a transformer and a mechanically driven switch to create a pulse. The voltage was unpredictable, dangerous and prone to failure because there were no-load peaks in excess of 10,000 volts and a rapid drop in voltage when the fence leakage increased. Later a solid-state circuit replaced the switch which improved the longevity and didn’t change the pulse width or voltage control

Modern fences today emit pulses of high voltage in intervals of time. They don’t take into account whether it is an animal or person (which would be grounded) touching the fence. It dumps the charge as soon as the conductive load touches the conductive wire.

Most fence energizers are hooked up to a permanent electrical circuit and put onto batteries or solar panels.

What are the uses of Electric Fencing?

Agriculture

Electric Fencing is very popular in agricultural areas. It is much cheaper and allot faster to erect than conventional fencing. The fence dis not restrain animals and the risk of injury to the animals is allot lower than this likes of barbed wire or wire that can entangle the feet. Also if the fence is touched an alarm can be set up to notify you that the fence has been touched and you can see in which zone to go and check.

Wild Animals

Electric Fencing is used for controlling the movements of wild animals. For example keeping animals off airport runways or animals from raiding crops, or deterring animals from private property like elephants.

Security

Non-Lethal electric fencing is fences that are built differently for perimeter security as opposed to animal management. It is there to deter potential intruders. The tampering with the fence sets off an alarm which is logged on the fence energiser, and a siren with strobe and if requested notification to a control room or message directly to the owner In other words, the electric fence serves as a sensor barrier that plays a part as a physical barrier and a psychological deterrent to intruders and works as a security alarm system.

What are the different types of Electric Fencing?

Piggy Back Fencing

This electric fence gets put behind an existing wire or mesh fence. It adds another layer to the existing security on a perimeter. How it works is it gets mounted onto the existing posts of the pillars of a palisade fence using rivets or screws.

Wall top Electric Fence

These are mounted on top of an existing wall. The electric fence should be at least 1.5m high.

Stand Alone Electric Fencing

This electric fence is a free-standing fence and works as the sole barrier. If done correctly, it is very neat. This is used for high-security areas or establishments. These electric fences have to be at least 1m away from the nearest barrier.
