Electric Fence Energizer: Find Your Match. Leave a comment
An electric fence energiser is the heart of any electric fencing system, providing the necessary power to create an effective deterrent for animals and intruders. Selecting the right energiser is crucial to ensure the efficiency, safety, and longevity of your electric fence. In this guide, we’ll explore the key factors to consider when choosing the best energizer for your needs.
The Concept of Modern Electric Fencing
An electric fence is a barrier designed to allow an electric current to pass along it. The system consists of a device called a power energiser.
These electric fence energisers have a length of a bare wire, a rod used to lead the electricity into the ground. The energisers may draw their power from a standard 230VAC outlet using a 230VAC to low voltage DC output (typically 12VDC). Alternatively a solar charged 12VDC battery is commonly used.
Every second or so, a pulse of high electrical energy is sent down the wire from the energizer to the grounding rod. Delivering a high voltage shock to whoever touches it, it serves as a potent stock management and animal pest measure.
The Main Components
What makes up an electric fence? A system consists of the following essential elements:
Electric fence energizers
An energiser acts as the powerhouse of your electric fence. Its job is to do a few electricity conversions to get high-voltage pulses. Once that pulse of electric current is generated, it will travel along the entire length of the fence. Each pulse only lasts a fraction of a second and produces roughly a second interval.
The type of energiser you need depends on how close the fence is to the main supply. Other considerations include how long the fencing will be and the animals you want to control
Conductor or the wire
You can use various types of conductors or wires for your electric fence. Steel wire, for one, is strong, durable and highly effective at conducting electricity. It is a suitable option if you want a greater but non-lethal shock effect when touching the fence. But it is heavier than other alternatives and ideal for permanent fencing solutions.
Alternatively, you can opt for polywire. This wire is UV-stabilised and great for temporary fencing and strip grazing. Other selections you have are polytape and polybraid. Both are highly visible and best for permanent and temporary fencing. They are more vulnerable in high winds, though.
Reels
A reel allows you to unroll the fence wire evenly without potentially damaging kinks. Then, you can roll it up again for reuse. By locking firmly onto a reel post, the reel also keeps the fence wire taut.
Stakes and posts
Permanent fences use timber posts to hold the fence wire. Metal or plastic stakes are suitable for temporary ones. Posts and stakes come in different heights and spacings, depending on the stock you want to fence. Electric fences running parallel to a public road are subject to signage regulations and installation requirements. Check with local authorities.
Insulators
Insulators stop the fence wire from touching the post or stake. In return, the electricity does not leak back to the ground. Anchor or end-strain insulators also take the strain of the wire at the end of the fence line or corners. Polystakes, made of non-conductive plastic, do not need separate insulators.
Look for good quality insulators that are smooth and easy to dry. These qualities help prevent moisture from collecting. Any leak in the arc will reduce the effectiveness of the fence.
Earth stakes
To work effectively, all electric fences have to be correctly earthed. Earth stakes are inserted into the ground and attached to the energiser.
How they work is simple. They ensure the power returns through the ground and back to the energizer. All this after a person or an animal completes the circuit by touching the fence.
Factors to Consider When Choosing an Electric Fence Energizer
When choosing an energizer, consider the following features:
Power Requirements
For selecting the appropriate energizer, understanding power requirements is key. You need to assess how much voltage is necessary for your specific fencing application, considering the types of animals you want to contain or deter. This can greatly influence the performance and safety of your electric fence system.
Fence Size and Type
Assuming you have a clear idea of your fencing layout, the size and type play significant roles in determining the energizer’s capacity. The longer the fence line, the more power you’ll need to maintain an effective charge throughout. Different fence materials also require varying voltage levels for optimal effectiveness.
When considering your fence size and type, think about the dimensions of the area you want to enclose and the material of the fencing. For instance, barbed wire, high-tensile wire, or polywire may require different energizer outputs to ensure animals receive an effective shock. Properly matching your energizer with the fence type is important for maximum performance.
Animal Type and Behavior
Choosing the right energizer hinges on understanding the animals you intend to contain or deter. Different animals have varying levels of tolerance and responsiveness to electric shocks, which should inform your choice of energizer voltage and power.
Understanding the type and behavior of the animals is crucial for a successful electric fencing solution. For example, livestock like cattle may require a higher voltage to ensure they respect the fence, while smaller animals like sheep may not require as strong a current. This consideration can prevent escapes and minimize stress on your animals.
Environmental Factors
Type of terrain and surrounding environmental conditions significantly influence your choice of energizer. Factors like vegetation, moisture levels, and soil types can all affect how well your electric fence performs, as these elements may cause additional drainage of the fence’s voltage.
Factors such as the amount of rainfall, humidity, and even the type of soil can dictate the performance of your electric fence. For instance, sandy soil may provide less conductivity than clay soil, requiring a more powerful energizer. Understanding these aspects will lead you to make informed choices that enhance the durability and functionality of your electric fence system.
Conclusion
Choosing the right electric fence energiser is crucial for the effectiveness and longevity of your electric fence system. By understanding your specific needs, evaluating key features, and investing in a quality product, you can ensure your fence performs reliably and safely. Whether you’re protecting livestock, securing your property, or safeguarding crops, the right energizer will provide peace of mind and long-term value.
