clamps to continuously connect the earth stakes and the energiser's Earth terminal. Make sure
the insulation is stripped back to ensure good contact between the wire and the earth stake.
The table below specifies the minimum number of 1m (3'3") earth stakes recommended for an
earthing system. Often, especially with bad conducting or dry soil more respectively longer
earth stakes are necessary.
P1500 / 1.0 J: 1 Earth stake
P2500 / 2.0 J: 2 Earth stakes
P3500 / 3.0 J: 2 Earth stakes
P3800 / 3.8 J: 3 Earth stakes
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 ground.
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 of
below 0.2 kV would be best.
