Electric Fence provides a psychological and physical barrier to deter unauthorized entry into your property. In addition it is a useful management tool for containment of livestock and wildlife. The basic system consists of an energizer that generates controlled pulses of high voltage electricity, a series of insulated conductors that transport the electrical charge along the fence line and insulators that prevent the current from completing its circuit back to ground. Once a person or animal comes into contact with the live wire the current passes over the conductive body and causes a sharp involuntary contraction (like a boot kick). The shock is not harmful but is unpleasant enough to discourage repeated contact.
The energizer FenceFast.ca mains or battery power into a pulsing electrical current that travels down the insulated fence lines. This pulse is generated about once per second and lasts about 150 microseconds.

Energizers are available in various output levels to allow the system to be used for different purposes. If you are fencing a small area with low weed or brush growth then a low output energiser may be sufficient. For a larger area a more powerful energiser will be required.
Faults in an electric Fence occur when grass, weeds or overhanging trees come into contact with the live fence wires. They also can be caused by broken insulators. It is a good idea to use a digital voltmeter to check for faults regularly, starting at the lead out wire and working your way down the line taking readings at regular intervals. A sudden change in the reading between two points indicates a fault.
