Note:
When earthing energizers located in dairies,
earth at least 20 m (65’) away from the dairy using
double-insulated lead-out wire to avoid touching
the dairy building or equipment.
Temporary electric fencing
A temporary fence can be quickly erected and easily
moved allowing the farmer to:
• Make smaller paddocks (fields)
• Keep herds of animals separated
• Ration feed
Note: Use more wires for smaller animals and wild
animals. Politape should be used when greater
visibility is required (e.g. horses).
An example of a temporary fence is shown below.
Frequently asked
questions/Troubleshooting
What voltage is required to control animals?
4 kV is widely accepted as the recommended
minimum voltage to control animals. However, you
also require a well constructed fence system to
ensure that animals cannot push through electrified
wires.
The fence voltage is below 4 kV. How do I
increase the voltage?
Check the energizer.
Disconnect the fence wire
from the energizer’s fence output terminal.
Measure the voltage across the energizer terminals
with a Fault Finder or Digital Voltmeter. If the
voltage is less than 6 kV, the energizer may require
servicing.
Check the energizer earthing.
Use the procedure
described in
Installing and testing an earth system
on page 76.
Check the fence system for faults. The most
common source of low voltage is faults on the
fence line.
If the fence, earth and energizer are in good
condition and the voltage is still below 4 kV, talk to
your nearest reseller. Recent extensions to your
fence, a poor fence layout, or soil conditions may
be causing inadequate voltage.
How do I locate faults?
The recommended tool for locating faults is a Fault
Finder. This combined voltage and current meter
allows you to rapidly locate sources of current
leakage. Alternatively, use a Digital Voltmeter. Use
cut-out switches to turn off the power to different
sections of the farm. If the voltage on the fence
increases when a section of the farm is turned off,
then investigate that section for possible faults.
There are no lights flashing on the energizer.
Ensure the power supply is on. Check the fence
system for faults (see above). Check the energizer
(see above). If the energizer still does not operate,
it may require servicing.
