Why Do Farmers Use Electric Fences?

Electric fences have become an integral part of modern farming practices for a multitude of reasons. With their ability to efficiently and effectively contain large livestock while simultaneously safeguarding them from potential threats, it's no wonder that farmers across the globe have turned to electric fencing solutions. The secret to their success lies in the use of an electrified current, which delivers a reinforcing shock upon contact. This unique approach allows farmers to utilize fence materials that are far smaller and simpler than traditional barriers, often consisting of just a few strands of wire.

How Does an Electric Fence Work for Cows?

Electric fences are commonly used by farmers to contain their livestock, including cows. But how do these fences actually work for cows? Well, electric fences work by creating a mental barrier rather than a physical one. Unlike traditional fences made of wood or wire, electric fences rely on an electric charge to deter animals from crossing the boundary.

For cows, the key is proper training. When cows are introduced to an electric fence, they quickly learn that it’s not something they want to mess with. When they come into contact with the electric wire, they receive a mild electric shock. This serves as a powerful deterrent and teaches them to stay away from the fence.

To ensure that an electric fence works effectively, farmers must regularly check the voltage using a fence tester. This device allows them to monitor the power output of the fence and make any necessary adjustments to maintain the desired level of voltage.

They’re relatively easy to install and can be more cost-effective than traditional fences. Additionally, electric fences can be easily modified or relocated if needed. This flexibility is especially beneficial for farmers who regularly rotate their grazing areas.

Proper grounding isn’t only important for the functionality of your electric fence, but it also ensures the safety of animals and humans. Without proper grounding, the electric current may not flow correctly, leading to a less effective deterrent for animals. In this article, we will discuss why you need to earth an electric fence and how to do it correctly.

Do You Need to Earth an Electric Fence?

Proper grounding is crucial for the functioning and maintenance of an electric fence. The fundamental principle behind an electric fence is the completion of an electrical circuit when any animal comes into contact with it. This electrical current begins at the energizer, travels along the length of the fence, and passes through the animals body to the ground.

By diverting the current into the ground, it prevents any potential risk of electrical shocks or injuries to animals, people, or equipment. Grounding also helps prevent any electrical surges or damage to the energizer, ensuring it’s longevity and effectiveness.

This interference can come from external sources such as lightning strikes or electrical equipment nearby.

These fences prevent animals from straying away, ensuring their safety within a designated area while deterring potential threats from entering. The electric current serves as a powerful deterrent, instilling discipline and preventing animals from testing the boundaries.
