HOW DOES AN ELECTRIC FENCE WORK?
An electric fence energizer converts mains or battery power into a high voltage pulse. The energizer releases this pulse on to an insulated fence line about once every second. The pulse itself is only around 150 microseconds long.
This pulse is commonly referred to as the "shock" and is felt by any animal which touches an electrified fence. When the animal makes contact with the fence the circuit is complete. It is at this point the animal receives a shock.
HOW DO I TEST THE EARTHING SYSTEM?
Test your earth system to ensure it’s working properly. To do this:
Turn off the fencer.
Short circuit the fence to ground at least 100 m away from the energizer. Create a fault by laying steel rods or pipes against the fence. In dry or sandy soils, drive the rods into the soil up to 300 mm.
Turn on the fencer.
Use a digital voltmeter to measure the fence voltage. It should be less than 2 kV. If not, repeat steps 1 - 3 using more steel rods or pipes against the fence.
Attach the voltmeter clip to the last earth rod of the earthing system.
Insert the voltmeter probe into the soil at the full length of the leads.
The voltmeter reading should be no more than 0.3 kV. If the reading is higher than this, the earth system is inadequate.
HOW IMPORTANT IS THE EARTHING SYSTEM?
Your earth system is the most important component of your electric fence. An effective earth system will optimise the performance of your electric fence.
HOW MANY EARTH BARS DO I NEED TO MAKE MY FENCE WORK?
Fencers can vary on how many earth bars are needed. Check out the link below for a more detailed answer for your Cheetah Fencers.
