Your common electric fence are going to be constructed from many posts, some conductive wire, rope or tape plus a battery or mains energy supply. The fence are going to be earthed at one particular end thus developing an open circuit. An electric present is pulsed around the fence passing by means of the electric wire, rope or tape until an animal touches it. By touching the wire an animal closes the open circuit. The current then passes by way of the animal and gets discharged into the ground, Electric fencing resulting inside a mild shock for the animal in question.
So there is the science, now what in regards to the strength of that shock? Is it the type of shock that could drop a cow? Well, the voltage of an electrical fence could be tempered to suit the size and strength of your animal. So for instance, it is actually protected to have a fence of 3,000 volts to get a horse whereas anything as much as five,000 volts is protected for sheep or goats. Either way, the shock delivered to the animal is designed to teach that animal to not touch the fence once again, not to harm it. The sensation delivered towards the animal is unpleasant but not painful or overly effective, farmers wouldn’t use an electric fence if it gave their sheep an afro every single time they brushed against it. Actually, an animal is far more most likely to hurt itself on a conventional post and wire fence than on an electrified fence.
Now for the other side of the story, yes its true that in the event the fence isn’t managed responsibly it could deliver a heftier charge, but a responsible and knowledgeable fence owner is not going to need to injure their animals any greater than a human, and electric fence controllers are very simple to operate. In fact, the vast majority of electrified fences are even safe through rain storms. Strict safety requirements also make certain that fences are secure to work with. So to summarise electrical fences provide a short, Electric fences safe shock that should not injure your animal, but will teach it to respect and prevent the fence thereby generating it simpler to contain. Exactly the same applies to any vermin that attempt to breach your fence in search of a meal. Most fences are built to strict safety requirements and can not harm humans or animals.
