An electric fence is an effective deterrent for many animals, including predators and scavenging animals. However, over time, the electric pulse can wear away at insulators and wires causing damage that requires repairs to keep the fence functioning correctly. Repairs can range from simple, like re-tightening loose posts or gates, to more complex, such as replacing the energizer or adding new wires.
One of the most common problems with electric fencing is low voltage. Low voltage could be due to a number of things, such as an insufficiently powered energizer or a lack of grounding materials. It could also be caused by a damaged or faulty insulator, such as from a falling branch or weed hitting the wire. It is essential to have a good quality energizer that is properly powered and grounded, with a minimum of 3 ground rods at least 6 feet long and 1 wire connecting all the ground rods to the energizer’s ground terminal.
Insufficiently insulated or conductive connections can also cause problems with electric fences. Insulators are designed to keep the electrical current running through the insulator, and when they break down or lose their ability to conduct, it can cause the energizer to short circuit. Using insulators rated for use with electric fences is important, as these will provide the best performance. Insulators can be replaced as they deteriorate, and the cost is relatively inexpensive.
A broken insulator on a live wire can result in a dangerous situation, especially for livestock or people. If the animal or person touches the live wire, they will receive a shock and possibly be injured. For this reason, it is recommended to regularly inspect the insulators on an electric fence. In addition to insulator replacement, it is important to regularly test the fence with a voltage meter or a battery-powered electric fence tester.
Another common problem with electric fencing repairs is poor earthing. A lack of grounding causes the electrical current to not return back to the energizer, and therefore the pulse is unable to stop the animal. It is also important to ensure that the energizer is connected to the ground and there are no breaks in the electrical wires on the energizer or grounding materials.
If your electric fence crosses public roads or walking, hiking or all-terrain vehicle trails, it is a good idea to post “Warning! Electric Fence!” signs to prevent unwanted accidents. It is important to teach children and adults not to touch an electric fence, as they can easily be hurt by the 8,000-volt pulse.
If an animal is constantly trying to jump over or wiggle through the fence, it may be a good idea to move them to a different pasture or cull them. A rogue animal can be a major waste of your money and time, and they should be taught a lesson before they continue to break your fences. This will save you money on repair costs and improve the longevity of your fences.
