6 Finding a Fault
The two most common faults in an electric fence installation are an open-circuit
(wire break, poor connection etc.) fault or a short-circuit (insulator breakdown,
vegetation, live and ground wire touching etc.) fault. In order to facilitate the
fault-finding process, current and voltage measurements at regular points along
the fence when in a healthy condition should be recorded for comparison when a
fault occurs.
6.1
Open-circuit Fault
•
Start as close as possible to where the high voltage (HV) leads from the
energizer connects to the electric fence and take a measurement on the
live wire.
•
Depending on the location of the open-circuit fault, the current might
be higher than for a healthy fence.
