THE ELECTRIC FENCE CIRCUIT EXPLAINED
AN ELECTRIC FENCE CIRCUIT CONSISTS OF FIVE MAIN PARTS:
1 The energiser produces regular current pulses.
2 The fence wiring transports the current along the fence. Insulators ensure that the current is not led away to the soil
3 When an animal touches the fence the current travels through the animal’s body.
4 The current travels through the soil.
5 The earth stakes carry the current back to the energiser.

THE ENERGISER (POWER SOURCE)
An ef cient energiser is the foundation of the basic power supply to your electric fence. The output power of an energiser is speci ed in joules.
Four factors play a crucial role when deciding which energiser to use:
1 Vegetation load on the fence
2 Fence length and conductivity of the wire used
3 Type of animal
4 Whether a permanent or temporary (moveable) system is required
You will nd detailed advice regarding the selection of an energiser in the tables for the particular energisers.
SUMMARY
Minimum power requirement depends on fence length and vegetation level:
Up to 500 m no vegetation – min. 0.25 joules
Up to 1000 m normal vegetation – min. 2.0 joules
Up to 1000 m heavy vegetation – min. 6.0 joules
0.33 joules / 9 volts 0.63 joules / Solar 12 volts
0.05 joules / 3 volts 2 joules / 12 + 230 volts
