Basic definitions
•
Electric Fence:
A barrier which includes one or more electric conductors, insulated from earth, to
which electric pulses are applied by an energizer
•
Connecting Lead:
An electric conductor, used to connect the energizer to the electric fence or the
earth electrode
•
Electric Security Fence:
A fence used for security purposes which comprises an electric fence and a physical
barrier electrically isolated from the electric fence
•
Public Access Area:
Any area where persons are protected from inadvertent contact with pulsed
conductors by a physical barrier
•
Pulsed Conductors:
Conductors which are subjected to high voltage pulses by the energizer
•
Secure Area:
An area where a person is not separated from pulse conductors below 1,5m by a
physical barrier
General requirements for electric security fences
Electric fences shall be installed and operated so that they cause no electrical hazard to
persons, animals or their surroundings.
Electric fence constructions which are likely to lead to the entanglement of animals or
persons shall be avoided, as entrapment can be lethal.
An electric fence shall not be supplied from two different energizers or from independent
fence circuits of the same energizer.
For any two different electric fences, each supplied from a different energizer with
independent timing, the distance between the wires of the two electric fences shall be at
least 2.5m. If this gap is to be closed, this shall be affected by means of electrically non-
conductive material or an isolated metal barrier.
Barbed wire or razor wire shall not be electrified by an energizer.
