Electric fence - glossary of terms

A

Amperage - The measurement of electric current, or what you feel when you get shocked. The higher the amperage, the more intense the shock.

B

Bracket - A device, normally out of metal, for supporting electric fencing wires.

C

Certificate of Compliance - CoC is a document issued by a registered installer, certifying that the electric fence installation complies with all the legal requirements and standards.

Circuit - Path through which electrical current flows.

Conductor - A material through which current readily flows. All metals are conductors.

E

Earth electrode - Metal device driven into the ground connected to the energiser ensuring a good conductive path of the electricity to the ground.

Earthing - The process of transferring the discharge of electricity directly to the soil. Earthing protects the people from electrocution and and equipment from damage.

Electric fence - An electrified barrier that consists of one or more conductors, insulated from earth, erected against the trespass of persons or animals.

Electric fence energiser - Fence charger; electrical device that delivers electrical energy to an electric fence.

Electric fence system - An electric fence plus an electric fence energiser.

F

Fence length - Length of the physical electric fence measured in meters.

Earthing - The process of transferring the discharge of electricity directly to the soil. Earthing protects the people from electrocution and and equipment from damage.

I

Insulator - A material which resists the electric current. Materials such as wood, plastic, and ceramics are insulators.

J

Joule - Unit of energy. A joule is one watt for one second.

L

Live wire -The wire connected to the energizer which carries the current.

O

Ohm - Unit of resistance to the flow of an electric current. A high ohms reading indicates a light fence load, while a low ohms reading indicates a heavy fence load.

P

Physical barrier - A barrier not less than 1.5m high with the opening no greater than 150mm, intended to prevent inadvertent contact with the electric wire.

Pulse - Brief electrical current emitted by the energiser.

R

Registered person - A person registered under the Occupational Health and Safety Act with a Certificate of Registration that proves sufficient knowledge of the safety standards.

Resistance - Anything that resists the flow of electricity on the fence, consuming power from a circuit. It is also known as "the fence load" and is measured in ohms.

U

Urban area - (High density population area) municipal/metropolitan areas or where population would exceed 400 or more persons per square kilometre.

V

Voltage - Measurement of electrical pressure which creates the current flow. Voltage “pushes” amperage down the fence wire. The higher the voltage the more amperage it can push.

W

Watt - Unit of power. Measures the rate of energy conversion or transfer.

Z

Zone - Length of electric fence powered by a single energizer.
