Electric Fence Terminology | Patriot Chargers
Posted by Patriot Chargers on
| AC | alternating current, AC (mains) power supply 110 – 120 V or 220 – 240 V. |
| Amp | unit of current. Short for Ampere. |
| Capacitors | used to store energy in the energizer (charger). |
| Current | duration and magnitude of current causes the shock of the electric fence. Increasing the voltage increases current, while increasing resistance decreases current. |
| DC | direct current, battery power supply (e.g. 12 V battery input). |
| Fault / Short | energy loss from the fence (i.e., live wire lying on the ground, vegetation growing over the fence, etc.). |
| Ground System | the rod(s) in the ground connected to the ground terminal on the energizer (charger). |
| Joule | unit of energy. One joule is one watt of power for one second. |
| Lead out Wire | section of underground cable or wire that carries the electrical current from the energizer (charger) to the fence. |
| Live | the current-carrying wire connected to the charger fence output terminal. |
| Ohm | unit of resistance. |
| Output Energy | effective energy delivered by the energizer (charger). |
| Pulse | brief electrical current given by an energizer (charger), approximately 0.0003 seconds per pulse. |
| Resistance | what causes loss of power and voltage on the fence. |
| Stored Energy | energy accumulated in the storage capacitor(s) in between output pulses. |
| Watt | unit of power. One watt is one joule per second. |
| Volt | unit of electrical pressure. Sometimes it is stated as “kV” or kilovolts which is equal to 1,000 volts. |
| Voltage | electrical pressure causing current to flow. |
