electric fencing circuit

How does an electric fence work?

In the most basic terms an energiser (pulser, fencer) converts mains or battery power into the pulse you want to run down your fence.  It is a high voltage pulse with low amps (very different to mains electricity).  The energiser releases the pulse along your insulated electric fencing at one pulse every second.  The actual pulse lasts around 150 microseconds!

The pulse or shock is what you feel if you touch the electric fence.  I wouldn’t advise it!

The shock is created because the circuit is completed if an animal touches the fence (see picture above).  The pulse travels along the electric fence and if an animal touches the fence it travels through the animal and into the ground and then back to the earth stake (the earth stake is very important and needs to be pushed into the ground as far as it can go)… creating a circuit and giving a zap!  This is the only circuit required with electric fencing – your actual electric fence doesn’t have to be connected back to itself.  The pulse enables us or an animal to get away from the fence.

The zap is a short lived shock – like a heavy static shock (ouch!).  This feeling creates a memory within us/or within an animal and we all know we don’t want to touch it again.  So, although the fencing is a physical barrier because it can be seen it is actaully more of a psychological barrier.  Animals learn to respect the fence and so stay away from it therefore keeping them safe and contained.

Electric fencing is a low cost and easily constructed alternative to stock fencing.  It can also be used to protect and improve existing fencing – add one or two lines of electric fencing run through insulators to an existing stock fence and you will extend the fence life.  Stock will also learn quickly to stay away from your stock fence.
