How to Determine Unidentified Faults by Inspecting Electric Fences?

When the electronic fence does not work or works abnormally, it will not be able to effectively protect the nomadic property. If there are unidentified faults, please complete the inspection of the electric fence in the following order.

Unplug or disconnect the battery before checking the power supply.

Energizers operating at 230 VAC must have a 220 to 240 VAC power source.

12-volt batteries should read at least 12 volts; 8.4-volt batteries should read at least 7.2 volts; 6-volt batteries should read at least 6 volts.

For best results, use a recreational battery rated at 70 amps/hour or higher.

 

1. Disconnect the fence wire from the exciter terminals. Do not remove the ground wire.

2. Use a voltmeter or other fence tester designed for testing fence power to measure the voltage between the fence and the ground terminal. Please note: ordinary voltmeters cannot measure very high voltages, short pulses, and may be damaged if connected across the output of the exciter.

3. If you don't have a voltmeter, you can use a short piece of insulated lead-out cable or a screwdriver with an insulated handle for a quick test.

4. Using a screwdriver or outgoing cable, draw an arc between the live terminal and the ground terminal. This should be between 1mm and 3mm. This is obviously not an accurate method but will give you an indication that the energizer is working.

5. If there is no arcing or low voltage, you should return the power to the hotline for repair, or you can replace the circuit board. If the output is normal, please check the fence installation.

 

1. Reconnect the outgoing cable to the Fence terminal on the exciter.

2. Disconnect the pinout at the fence and check the voltage.

3. If the voltage is normal, the pinout is good.

4. If the voltage is low, the lead wire is faulty and must be replaced. Use only double insulated cables rated at 20,000 volts. HT/G cable, or a copper HT alternative (less strong, but more conductive).

5. Reconnect the outgoing cables to the fence and disconnect any fences extending from the main fence, or divide the fence into sections.

6. Check the voltage. If the voltage is low, the fault is at the main fence or the first section. If the voltage is normal, reconnect the fences or sections, checking the voltage as each fence or section is added. The voltage should remain constant or drop slightly before connecting the fence or section that is causing the problem. Then the voltage will drop drastically or the fence will short out completely.

7. Look carefully at gates, where cables are laid underground, around corners, and where fences are close to other fences. Pay close attention to insulators, joints, and connections. Listen for a cracking sound indicating a short circuit.

8. Vegetation or rust on fence lines is the most common cause of voltage loss. If enough weeds or grass touch the fence, high-powered generators can lose voltage, especially when wet.

9. Spraying herbicides under fence lines is a good management practice.
