Positive / Negative electric fence

An electric shock can only be received when somebody touches both the positive and negative contacts at the same time.
In electric fence systems, the negative contact is grounded.

No grounding – no electric shock.
This phenomenon is familiar to anyone who has seen birds sitting on high-voltage power lines.
Similar things happen when, for example, animals climb up onto a wooden fence and touch an electric cable.
In this case too, the animal does not receive an electric shock and the electric fence is ineffective.

The solution to this is a positive / negative electric fence!

With this special type of electric fence you can keep or deter animals even if they don't make direct contact with the ground.

Areas of application for positive/negative electric fences:

Animals that do not make contact with the ground, such as

  • martens on carports, in gutters ...
  • raccoons on house walls, on drain pipes ...
  • cats standing on panel fences ...

areas with poorly conducting ground conditions, such as

  • dry soil
  • stony soil
  • snow-covered soil

Details of Positive-Negative electric fence

With a positive/negative fence the wires are alternately connected to the fence connection (positive terminal) and the ground connection (negative terminal) on the energiser. These wires are separated by a distance that is too small for the animal to slip between them without touching both at the same time. When two wires are touched simultaneously, an electric shock is felt. The current flows directly from the fence wire (positive terminal), through the body that is touching both wires to the ground wire (negative terminal).

An electric shock delivered in this direct manner is on the one hand very intensive, but on the other is much gentler on the animal as the current only flows through a small part of the body (compare this to how a conventional electric fence works).
