Electric Fence Security System
The heart of an electric fence system is the energiser (power unit). The electric fence energisers a necessity. This box is filled with capacitors that store the charge. The electric fence charger (energiser) converts mains or battery power (240 volts) into a high voltage pulse (non-lethal shock). It also controls its movement down the wires, every 1.5 seconds. Energisers have a low energy consumption and you will not see any noticeable increase on your electricity bill.
If you are using a battery as power, keep in mind that the battery needs to be replaced every 2-3 years. Also keep in mind as the battery looses charge, so does your electric fence. It is a lot more convenient to run off mains.
For an electric shock to occur, the current must complete a full circuit, as in diagram for electric fence. When a grounded person touches the wires of the fence, the electric fence circuit is complete. Electricity flows through the body and back through the ground to the earth, to return to the terminal of the energizer. It is at this point that a person receives a shock from electric fence and hopefully has experienced enough discomfort to lose interest in trying to climb over your wall.
Discharge of current from the live terminal of an energizer is about 7000 volts. Not all this current actually ends up on the fence. This is known as voltage leaking. Electric fence manufacturers state these numerous scenarios will determine how many volts actually end up running through the wires. These include:
The condition of the wiring and connections
The type of fencing wire you are using
How well the live wire is insulated
An ineffective earth system
Vegetation touching the wires
An electric fence will only work if the electrical wiring is earthed. Gate Repair Services technicians have seen unearthed electrical fence installations by previous installers, much to the customer’s horror!
