Temporary electric fencing
PATURA offers a range of products that allow the farmer to construct a temporary electric
fence. A temporary fence that can be quickly erected and easily moved allows the farmer to:
• Make smaller paddocks (fields)
• Keep herds of animals separated
• Ration feed
Note:
Use more wires for smaller animals and wild animals. Polytape should be used when
greater visibility is required (e.g. horses).
Installing and testing an earth system
Select a suitable site for the earth system. Sites need to be:
• At least 10 m (33') from other earth systems (e.g. telephone, mains power or the earth
system from another energiser).
• Away from stock or other traffic that could interfere with the installation.
• At a site that can be easily observed for maintenance.
• Ideally at a site that has damp soil (e.g. a shaded or swampy location).
Note that the earth does not need to be directly adjacent to the energiser installation.
Drive the PATURA earth stake into the ground. Connect the green earth lead from the energiser
to the earth stake.
Often, especially with bad conducting soil or dry soil more respectively longer earth stakes are
necessary. Continuously connect them with the existing earth stakes respectively with the earth
terminal on the energiser. Provide a good connection. The length of the earth stake should be
at least 0.65 m.
Test the earth system, using the following procedure:
1. Turn off the energiser.
2. At least 100 m (330') away from the energiser, short circuit the fence by laying several
steel stakes or lengths of pipe against the fence. For best results, the fence voltage should
be lowered to 2,000 V or less. In dry or sandy conditions, it may be necessary to drive the
stakes up to 300 mm (12") into the earth.
3. Turn the energiser back on.
4. Using a PATURA Digital Voltmeter, ensure that the fence voltage is below 2 kV.
5. Check your earth system. Insert the voltmeter's earth probe into the ground at the full extent
of the lead, and hold the hook against the last earth stake. The tester should not read more
than 0.5 kV. Anything higher than this indicates that better earthing is required. Either
add more earth stakes or find a better ground area to drive in the earth stakes. A voltage
below 0.2 kV would be best.
