When an animal touches the live conductor while in contact with the ground, the electrical circuit is completed through the earth system.\u003c\/p\u003e\n\u003cp\u003eVoltage and joules describe different aspects of energiser performance. Voltage helps the pulse overcome resistance and deliver an effective deterrent, while joule ratings indicate the energy associated with the pulse. Your choice should therefore account for total fence length, conductor type, expected vegetation and the animals being contained.\u003c\/p\u003e\n\u003cp\u003eEarthing is equally important. Poor earth contact can substantially reduce fence performance, particularly in dry ground. Follow the energiser manufacturer's installation instructions for the number, positioning and depth of earth stakes, and keep connections clean and secure.\u003c\/p\u003e\n\u003cp\u003ePro tip: use an \u003ca href=\"https:\/\/www.onlineforequine.co.uk\/collections\/electric-fence-testers\"\u003eelectric fence tester\u003c\/a\u003e at several points around the fence rather than assuming that a flashing energiser means the entire system is performing correctly.
