An electric fence energizer converts mains or battery power into a high voltage pulse. The energizer releases this pulse on to an insulated fence line about once every second. … When the animal makes contact with the fence the circuit is complete. It is at this point the animal receives a shock.
How does an electric fence charger work?
The energizer pushes an electric pulse through its “+” terminal to the fence. The pulse travels through the conductors and pressurizes the fence with excess electrons. That pressure is measured in volts. When an animal touches the fence, excess electrons enter it and travel through the animal to the soil.
What triggers electric fence alarm?
The fence will go to alarm if: The fence is earthed for 3 pulses/seconds (shocks someone/something) OR if a live wire and an earth wire make contact for more than 3 seconds OR of a live wire is cut. The siren would then sound.
Does an electric fence have to make a complete loop?
No. An electric fence circuits flow relies on passing through a conductive object (usually an animal) and into the physical earth or ground itself (as shown in this picture). … So an electric fence does not have to make a complete loop to be an effective barrier or an effective circuit.
What is the output of an electric fence?
Many manufacturers claim their energizers can power 8-20 miles/joule of output, but these are numbers obtained under ideal laboratory conditions. In practice, if you have a one- or two- strand fence that is free from weeds, tall grass, and branches touching it, you might get 3-6 miles/joule.
Can electric fence wires touch each other?
Wires tend to flip due to the wind. Many people tend to install in-line strainers above each other, but this is not the right way to do it. You should separate them by a fence post so that they don’t catch on each other.
How do you turn off an electric fence alarm?
Switch the unit off with the Nemtek tab or remote key-switch. This will silence the siren (if it has not already timed-out), internal buzzer and will switch the strobe off. One of the alarm lights will be flashing or will remain lit to indicate the source of the alarm.
Why is the ground wire hot on my electric fence?
For those of you that have an electric fence installed, ground wire heating can be a problem. Generally, the ground wire completes the circuit of the current flow in the fence. … But if you notice that it’s heating up, the most probable cause is leakage or improper grounding installation.
What happens if you don’t ground an electric fence?
When an animal comes in contact with an electric fence, a pulse travels from the fence, through the animal and into the soil. Via the soil moisture, this pulse is captured by the ground system and returned to the energizer. Without proper grounding, the fence’s electrical circuit can not be completed.
How many grounding rods do I need for an electric fence?
In fact, the majority of electrical fence systems will actually require at least three grounding rods. These rods should be about 10 feet apart and should be placed at the start of the fence.
How far apart should ground rods be for electric fence?
A general rule is to install a minimum of 3 feet of ground rod per joule of output capacity. A 15 joule fence charger will require a minimum of 45 feet of ground rod. These rods must be installed at least 10 feet apart from each other.
