When an electric fence is energized, a brief pulse of high voltage travels down the wires. If an animal touches both the conductive wire and the ground simultaneously, the circuit is completed, giving the animal a painful shock. The animal then learns to avoid the area.

To achieve the greatest effectiveness, you should always keep your electric fence properly insulated and grounded. Insulators prevent electricity from leaking into grass, plants and other conductive objects, reducing the risk of unintentional shocks. Grounding helps to complete the electrical circuit and reduce the shock intensity. It is important to regularly check the electrical current of your electric fence, especially during changing weather conditions, as dew, fog and rain can decrease the voltage.
Secure Your Space: A Comprehensive Guide on Where and How to Buy the Right Electric Fence
It is recommended that you use a good quality, dependable energizer and that you purchase one that has more energy (joules) than you will think you need. When comparing different energizers, look at both the output joules and the stored joules. Output joules indicate how much power the energizer will send down the conductive wires, while stored joules indicate how much energy it can store in its capacitors.
Use a voltmeter to test the fence, starting at the lead out wire and working your way along the fence line, taking readings every 10 feet or so. A sudden change in reading between two points indicates a fault, and should be corrected as soon as possible. A digital voltmeter is ideal for this task and is available from Dare.
