More safety due to a better grounding
If the grounding of the electric fence system is unattended, the performance is decreased and can result in a higher risk of break-outs of the animals. We recommend the use of several earth posts so that you can always be sure.
In practice, a good grounding of the electric fence is often unattended. The consequence: less performance from the construction and a higher danger of animal break-outs.
The operable electric fence is an open circuit. The circuit is closed and the energy flows through the body into the earth. A connection between the conductor and the earth is established. If the current pulse flows through the animal's body, a shock is triggered (reaction of the nerves). This shock guarantees the scaring impact of the electric fence. The electricity flows through the ground and the earth posts back into the electric fence.
A good grounding and therefore a high pulse intensity is generated as much as possible by low earthing resistance. If the soil does not conduct the electricity because of too short or not enough earth posts the fence cannot work and the circuit is disconnected. Therefore we recommend the use of several earth posts, so that you can always be sure.
- Dry ground should always be avoided, because wet soil conducts the electricity much better.
- With dry ground, further earth posts can be added.
- Rust generates a bad grounding, therefore the earth posts should be made of rust-proof material.
- The longer the earth posts, the lower the resistance and the bigger the surface, the better the connection.
- A powerful electric fence needs a better grounding than a weak electric fence.
- A minimum distance of approx. 10 m should exist between different grounding systems (especially with house groundings).
