An electric fence works as a deterrent to animals, birds and other pests that would try to cross your property boundary. An animal that touches an electrical fence feels a short involuntary muscle contraction which may be uncomfortable, but not dangerous. An animal that feels this sensation once will learn to steer clear of the fence line and will never attempt to cross it again. The most common uses for electric fencing include animal exclusion, strip grazing and security.
An electrical fence is powered by an energizer which pushes a pulse of electricity through the positive terminal of the wires (shown left) every millisecond or so. This pulse creates a pressurise effect on the fence lines which carries excess electrons from the positive terminal back to the negative ground terminal through an insulated conductor like poly-tape or a wire fence. This is why it is so important that you only use high quality insulated wire and not a cheap hose clamp holding copper wire to a rusty t-post.
The voltage and strength of the pulse is what determines whether or not you get shocked and the intensity of the shock. Most Gallagher energizers produce an average of one hundred millionths of a second with at least one second between pulses so it is unlikely that you will ever feel anything more than the slight discomfort of a sudden, brief muscle cramp.
Most Energizers have a built in safety feature which will cut off the flow of energy when a live touch is detected. This is designed to prevent you from getting an electric shock and will also protect your energizer from damage due to too much voltage flowing through it.
The polarity of the wires should be checked regularly to ensure that they are correctly connected. Most polarity issues are caused by incorrect wiring or connections between the positive and negative grounding terminals of the energizer. Always make sure that both of these are securely attached (never use a hose clamp to connect these two terminals together).
A good grounding system is essential for most systems. This will allow you to reduce the amount of power needed for your electric fence malaysia and it will stop the current from leaking onto conductive surfaces like dry ground or metals in case of a fence fault.
A proper grounding system includes a minimum of three ground rods spaced apart from each other and with adequate cable length to reach the positive and negative terminals on your fence energiser. Each of these rods should be properly insulated with plastic insulators from any conductive material including the ground, grass, trees and concrete. Some energizers also have an Earth leakage monitor which will display an icon on the LCD screen when a problem occurs with the grounding system. This can help you identify and correct any problems early on before they cause a permanent power outage or even a fire in your yard. This is an important safety feature and all Gallagher energizers are engineered with it in mind.
