Temporary Electric Fencing; Safety Considerations - stafix Cyclic Wave B6 Mode D'emploi

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 Stafix earth rods into the ground. Use high-
voltage, insulated cable and earth clamps to
continuously connect the earth rods and the
energiser's Earth terminal. Make sure the insulation is
stripped back to ensure good contact between the
wire and the earth rod.
The number of earth rods used will vary with the soil
conditions. For larger energisers, at least six 2 m
(6'6") earth rods are required. To ensure that an
adequate number of earth rods have been used, test
the earth system using the following procedure:
Turn off the energiser.
1
At least 100 m (330') away from the energiser,
2
short circuit the fence by laying several steel rods
or lengths of pipe against the fence. For best
results, the fence voltage should be lowered to
2000 V or less. In dry or sandy conditions, it may
be necessary to drive the rods up to 300 mm (1')
into the earth.
Note: It is not acceptable to short circuit a fence
return system to the earth wire of the fence.
Turn the energiser back on.
3
Using a Stafix Digital Voltmeter, ensure that the
4
fence voltage is below 2 kV.
Check your earth system. Insert the voltmeter's
5
earth probe into the ground at the full extent of
the lead, and hold the hook against the last earth
rod. The tester should not read more than
0.3 kV. Anything higher than this indicates that
better earthing is required. Either add more earth
rods or find a better ground area to drive in the
earth rods.
Note: When earthing energisers located in dairies,
earth at least 20 m (65') away from the dairy using
double insulated wire to avoid touching the dairy
building or equipment.

Temporary Electric Fencing

Stafix 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. Politape should be used when greater
visibility is required (e.g. horses).
An example of a temporary fence is shown below.

Safety Considerations

Definition of special terms
Electric fence energiser – An appliance that is
intended to periodically deliver voltage impulses to a
fence connected to it.
Fence – A barrier for animals or for the purpose of
security, comprising one or more conductors such as
metal wires, rods or rails.
Electric fence – A barrier which includes one or more
electric conductors, insulated from earth, to which
electric pulses are applied by an energiser.
Fence circuit – All conductive parts or components
within an energiser that are connected or are
intended to be connected, galvanically, to the output
terminals.
Earth electrode – Metal structure that is driven into
the ground near an energiser and connected
electrically to the output Earth terminal of the
