<p>The system defends shallow water or flat banks from penetration by rodents or reptiles, it has a series of straight electrical conductors parallel to each other, those earthed alternating with those connected to an AC power source. A dyke (2) emerging from the water level (1) electrical conductors (4) which are bare for at least part of their length at intervals along the dyke. The intervals between the conductors are approximately equal to the length of pace of the animal to be eliminated, and for which the AC frequency and voltage is lethal.</p> |
