Tips on the use of Electric Fencers


Tips on the use of Electric Fencers – Killyless Stores

Farm fencing in Ireland can be divided into two categories:

  • Temporary Fencing
  • Permanent Fencing.


Temporary Fencing is used to enable farmers to control livestock by using a Dry or Wet Cell battery fencer, plastic or steel posts and with tape or polywire to fence the area required.


It is ideal for controlling paddock size and optimising use of wet areas. By using  battery or solar powered fencers, temporary fence posts, tape or polywire farmers can control livestock, reduce land damage and increase profits through better pasture management.



The use of battery powered fencers means batteries have to be either recharged or replaced at a serious cost of both time and money to the farmer.

Solar Powered Fencing is a low cost, efficient and effective way of controlling livestock in areas where mains power is not available. They are designed to work in our climatic conditions and give adequate voltage on the fence wire to control livestock under vegetation growth conditions ie 100 Ohms resistance.

By using a  Solar Fencer, farmers can permanently fence outfarms without having to worry about the battery running down or having to recharge or replace batteries. They can manage paddocks more efficiently, improve pasture management, increase profits and achieve peace of mind. To date we have many thousands of units working satisfactorily in Ireland and the UK.


  • Removes cost of replacement batteries.
  • Battery charged during daylight hours.
  • Removes problem of recharging batteries.
  • Continuous charge prolongs battery life.
  • Is reliable and cost effective.
  • Is environmentally friendly.


Permanent fencing consists of 1 single strand of 12.5 gauge galvanised wire erected permanently using a high output joule fencer and high quality insulators and accessories. Three or more strands may be needed for control of sheep.

Usually erected around the farm boundaries, farmers then subdivide the area into paddocks by using a reel, polywire and plastic or pigtail posts. By using the backgrazing method farmers can adjust the paddock size according to number of livestock or grass growth conditions.

Just as higher water pressure in a pipe leads to more water leakage, high voltage on a fence wire leads to greater power loss through small or poor quality insulators. All electric current wants to get back to source. Therefore power on the fence wire wants to get back to the fencer via the earth field. Remember 10 volts lost through each of 100 insulators amounts to 1000 volts lost off the fence wire.


Permanent Fencing Explained:Temporary Fencing is ideal for livestock control where permanent fencing is not an option. It is low cost, versatile and can be adapted to meet any situation. It is ideal for out farms, rented land or anywhere where short term livestock control is required.

Understanding Fencing Terms:

Voltage:                       Power on the wire that controls livestock.

Joules:                          The horsepower of each fencer that drives volts along the wire.

Stored Joules:           The horsepower in the fencer.

Output Joules:               The real horsepower of the fencer: Approx two thirds stored joules.

Eg. 15 stored joules= 10 output joules.

Testing Your Fencer:

No Load:                     Voltage in the fencer.

500 Ohms:                   Voltage on wire under perfect conditions.

100 Ohms:                   Voltage on wire under grass growth conditions.

Note: Voltage on fence wire should not drop below 2000 volts for effective livestock control.

Choosing a fencer:

  • 1 output joule will drive volts along 6 miles/10km of wire in perfect condition.
  • Decide on area and type of land to be fenced.
  • The type of stock to be controlled.
  • Choose a fencer larger than required to allow for fence additions.

Erecting your fencer:

  • Erect fencer in a cool, dry, well ventilated shed.
  • Erect fencer out of reach of children or animals.
  • Connect  underground/ lead out wire from fencer terminal to fence wire.
  • Connect  underground/ lead out wire from fencer terminal to first earth rod.

Earthing your fencer:

  • Choose an earth site that is moist and a least 33ft (10 mtrs) away from:
  • –         Any earth stake for any other electrical system.
  • –         Any telephone earth stake.
  • –         Any water pipes including disused water pipes.
  • –         Any building using structural steel or reinforced metal in the ground.

NB: Never choose an earth site near a dairy or milking parlour.

Why we use Output Joule Technology:

Our moist climate, long growing season and retention of hedges places more pressure on farm fences. Heavy vegetation growth places a resistance of 100 Ohms on fence wire, The minimum voltage required to control livestock is 2000 volts. The Joules or Horsepower in an output joule fencer will reach maximum output joules at maximum resistance on the fence wire, ie 2000 volts minimum under heave vegetation growth. They are designed to give adequate voltage on the fence wire under heavy vegetation growth.

In Ireland a 5 output joule fencer would fence between 60 and 70 acres because of the reasons stated above. In Europe or any country where summers are drier and the removal of hedges would enable a 5 joule fencer to fence about 300 acres.
