Electric fences rely on animals’ natural instincts and behavior to control and deter them. They can be used to keep out pests and protect livestock and crops.
Most modern electric fences use a component called a power energizer to convert AC power into short high voltage pulses. Modern energizers also incorporate a system of alternating hot and ground wires, which prevents people or animals touching both hot and ground simultaneously.
Animal Control
Electric fencing is used to prevent trespass by animals by causing an uncomfortable, but not necessarily lethal, shock when it is touched. It is also used around industrial facilities, commercial warehouses and offices, apartment complexes, manufacturing plants, and prisons to protect property and deter unauthorized trespass.
Modern electric fences use a component called an energizer that converts standard household electricity into high voltage pulses for a few milliseconds each second. One terminal of the energizer is connected to the bare wire, and another to a rod embedded in the ground. When an animal touches both the bare wire and the rod it completes the circuit and causes the shock.
An electric fence requires a constant power supply or it will be ineffective, especially for preventing predators from entering crops. It is recommended that you check your fence regularly using a tester to ensure that it has sufficient voltage.
Deterrent
Electric fence systems capitalize on animals’ instincts and behavior to deter them from crossing the boundary. They work by delivering an unpleasant but harmless electric shock to animals that come into contact with the wires.
The energizer converts mains or battery power into a high voltage pulse that runs along connected bare wire. When an animal touches both the energizer terminal and a metal rod implanted in the ground, it completes an electrical circuit and receives a brief pulse of electricity.
Modern energizers use thyristors to charge capacitors and deliver a short high voltage pulse, about once per second. This reduces the deadly amperage to a fraction of what is used for household appliances and should not harm humans or livestock, even if it was to be continuously supplied for hours.
Keeping your system up and running requires regular inspection and maintenance. This includes checking the condition of the insulators, removing vegetation from the insulated sections, and making sure all connections are secure.
Security
Electric fence malaysia are a highly effective deterrent to criminals and trespassers. They are usually low voltage and therefore not lethal unlike barbed wire which can cause severe and lasting pain. They also do not damage the animal’s hide and are therefore a non-lethal physical barrier to intruders.
Electric fencing requires a component called an energizer to power it. An energizer converts electricity to brief pulses of high voltage and sends it down a series of connected bare wires or tapes (conductors). The Energizer also has a terminal that is attached to a rod placed in the ground, called the earth terminal. If an animal touches both the conductor and the earth during a pulse they will complete an electrical circuit and receive a shock.
A thyristor is used in modern energisers to control the current. The pulse is a fraction of the current a welder uses to burn steel. This is enough to injure an animal or human but not sufficient to kill them unless they remain touching the fence wires for extended periods of time.
Safety
Electric fences can be effective in containing horses if they are properly configured and connected to an energizer that has a high output. These units push electric pulses out through their positive fence terminal and absorb any excess energy on their negative ground terminal – a galvanized metal rod driven into the ground.
Modern fence energizers use low-impedance circuitry that charges a capacitor through a solid-state circuit and releases the charge with a thyristor. This allows for a more controlled voltage delivery and a shorter shock pulse that is only felt for a few milliseconds.
When an animal touches a live electric fence they get a painful cramping sensation that will cause them to avoid the fence in the future. They will also learn that if they try to jump over or through the fence, they will be shocked again. This can be a very effective deterrent for both predators and herbivores, and can reduce the need to construct costly physical barriers.
