10. SECTOR SETUP TESTS AND
With a single sector system there are two considerations for the electric fence
monitor voltage level:
1. The monitor should trigger the alarm if one of the live wires is shorted to ground.
2. The monitor should trigger the alarm if one of the live wires is cut.
Use common sense and turn the energizer off when making changes to the fence,
then turn the energizer back on to check the effects.

10.1 Basic Fence Tests

1. Energise the newly-completed fence.
2. Use an Electric Fence Power Probe to find any construction faults.
3. Check that there is voltage on all live wires (continuity) and that there are no
shorts from live to earth, or between live circuits (Bi-Polar).
4. Check the electric fence earth. (See electric fence manuals.) One method is to
make an intentional short from live wire to earthed metal (not +ve to -ve if using
Bi-Polar). The voltage at the earthed point should be less than a few hundred
volts; the voltage on the earth stake with respect to any nearby earthed metal
should be less than a few hundred volts.
5. Record the start and end of fence live wire voltages.
NOTE: Bi-Polar systems should have approximately equal voltages with respect
to earth.
6. Record the live wire currents going out from the energizer to the fence.
At this point you must have a reasonable voltage on all parts of the fence. To be
an effective barrier, the Power Probe (or voltmeter) readings between wires (live to
earth or +ve to -ve for Bi-Polar) must be greater than 5.0kV. If they are not, then you
may require a larger energizer.
