How many lines to build? At what height?
General idea of the electric fence
Principles of an electric fence Farmcomp Oy
This is how an electric fence works under normal conditions
The animal touches the fence and the ground at the same time = gets a light electric shock.
Principles of an Electric Fence Farmcomp Oy Electric fence energiser produces the high voltage impulses every second and sends them to wires / tapes / ropes. When an animal touches the fence, electricity goes through the body of an animal to the ground. The animal gets a light electrical shock and goes away from the fence. The electric shock is not dangerous for an animal but teaches the animal not to approach the fence any more. Power suply options of an electric fence energiser: Mains 220 V
Battery 9 V or Rechargeable battery 12 V
Solar panel
Basic rules on choosing a suitable model of an electric fence energiser. If possible always choose a mains supply energiser – Cheaper to use Basic models:
Use a powerful energiser when:
Olli 1200/1800/2000
- Fencing animals with long or thick fur
Olli 600/950/1200/1800
- The first strand of a fence is too low (risk: grass/bushes might touch the fence which would cause the electricity to leak) - Building a long fence
Olli 100/300/600/950/1000
- There are male animals in the herd
Measuring and marking the territory Installing posts for building gates: 1. Make a decision on how long a fence you want, where and how many gates you want, then where the energiser will be. 2. Install posts for the gates. A gate should allow animals, humans and machines to easily pass in and out of the gate. 3. Install posts for the whole length of the fence (on the whole perimeter of the fence). 4.4. The height of the posts should be the same on the whole length of the fence (relative to the terrain). The distance between posts should be determined according to the terrain. The more height differences, uneven surface , ditches there are on the land, the shorter the distance between the posts. Maximum distance between the posts: 8 meters. 5. The Corner Posts need to be strengthened to support the stress put on them by the ropes and tapes. Size of the gate Size of the gate may vary between 2,5 m an d4,5 m. Spring gate: 4,5 m Rope gate: 3,2 or 4,5 m. When you build a gate using only gate handles and gate insulators, distance between the posts in the gate should be from 2,5 to 3,5 m.
Spring Gate
Rope Gate
Building the spring gate Assembling the gate: 1. OLLI-spring gate consists of a spring, isolated gate handle and gate insulators. Isolated gate handles allow you to open and close the gate without switching off the fence energiser. 2. Determine the appropriate height of the lines in the fence. Height and quantity of lines in the fence is determined according to the specific recomendations for different kinds of animals. Order of the assembling: 1. 2. 3. 4.
Install posts for the gate Screw gate insulators into the posts Attach the gate handle to the spring Attach the spring gate to the gate insulators
Installing a rope gate 3,2-3,5 m 1,2- ~ 2,5 m
Gate closed Gate open
! Rope gate
Installing the insulators Installing the insulators in the electric fence: 1. Place the posts to the whole length of the fence. 2. Determine the height of the lines. 3. Height of the lines is determined according to the specific recomendations for each kind of animal. 4. Screw the insulators to the posts using a special tool. 5. Check that all the insulators are installed with the place for the wire upwards.
Important! When using wooden posts it is necessary to use the insulators because wet wood causes the electricity to leak out of the fence. Wires and Tapes should not touch the uninsulated elements of the fence. This can cause serious damage to the energiser.
Installing Tapes or Wires Installing tapes or wires: 1. Attach a wire to a gate insulator using a special connector, Make several turns over the gate insulator hook so that the wire is tightly attached to the insulator. 2. Tighten the connector to ensure good electrical contact. 3.Connect lines of the fence with each other. Make connections between the lines each 200300 meters to ensure electricity flow in the whole length of the fence. 4. Check the connections.
Building the fence Wire / Rope fence
Connect lines of the fence to each other
Continue building the lines under the gate with the OLLIundergate cable. This will ensure good electricity flow under the gate.
Installing the connectors
Connecting wires To ensure good electrical connection, use special OLLI-connectors. Usual connectors easily rust and stop electricity flow in the fence.
Order of assembling: 1. Place the wire to the connector 2. Tighten the connector to ensure good electrical contact
Choose high quality wires and connectors
Important! Don’t connect the wires with a knot! Knots do not ensure good contact and as a result cause sparking. Sparking heats the wires and cause damage to it. Sparking can also cause interferences to radio and TV frequences.
←The high quality Olli connector - Stainless Steel - Allows connection to be tight - Crosses all wires Any vegetation – Grass, Bushes, Trees, or wood and metal directly on the fence wires will cause the fence to leak electricity. It reduces the power going through the fence, when it has been raining the electricity can also ”jump” (Sparking) to a post if the insulator is broken or poor quality. We recommend checking the fence every week or after a storm.
Don’t do this!!!
Installing tensioners
Tensioning wires Tensioners are used to tighten the whole length of the fence. When wires are well tightened, it keeps them more protected from winds and allows a longer life of a wire. Order of installation: 1. Put a wire to the tensioner 2. Tighten the wire until it’s straight and tight. 3. Tie off the rope.
Installing the energiser
Installing the energiser: 1. Attach the energiser to the post with the screws included in the delivery
2. Place the Olli earth stake near the energiser. 80 cm of the earth stake should be put into the ground. For dry/sandy ground use several earth stakes.
Order of installing:
1. Attach the energiser to the post 2. Put the earth stake 80 cm to the ground. 3. Connect the energiser to the power supply.
Make Sure the earthing is good ! IMPORTANT: Use only OLLI-zinc covered earth stakes. Low-quality earth stakes rust easily and stop the normal functioning of the fence. You will need 1-3 earthing stakes depending on how powerful energiser you choose, how long fence you are building and how dry the ground is nearby. Place the earth stakes at the distance of 1 m away from each other. Earthing of an energiser should not be connected to the earthing of buildings, general earthing or water pipe. According the safety instructions, electric fence energiser should be earthed a safe distance (at least 10 m) away from the earthing of buildings (or water pipes).
The best place for the earthing stake is near any water (for example near the swamp, lake or river). Never put an earthing stake under the roof or under the buildings because dry ground is a very poor electrical conductor!
That’s why it is highly recommended to use OLLI-undergate cable for making good earthing, It is most important when the energiser is situated in the building and the earthing should be made out of the building. If the earthing of an energiser is connected to the water pipe, it can cause light electrical shock e.g. in the shower. If connected to the earth of a building or general earthing of the electric network, it can cause interferences in the functioning of electrical and radio devices e.g. phone,
Connecting the energiser Connecting the energiser:
1. Install lightining protector, it prevents damage to an energiser if it is struck by lightning. Connect the lightning protector to the fence. 2. Connect the energiser to the earth stake and to the lightning protector. 3. Connect the energiser to the power supply. Note; ”+” = Positive
”-” = Negative/Earth Order of connecting: 1. Install lightning protector. 2. Connect lightning protector to the fence, 3. Connect the energiser to the earthing stake and to the lightning protector. 4. Connect the energiser to the power supply.
Optional lightning protector installation
Testing the fence
Measuring voltage in the fence: Switch the energiser on and check the voltage on wires and connectors using the tester. There shouldn’t be sparkling in any part of the fence. If you can hear clicks at the places of connection, this is a sign of a bad connection and sparkling. Sparkling warms the wires and causes serious damages to the fence.
Order of testing: 1.Earth the tester 2.Check the voltage at the places of connections. 3.Check voltage on the wires. Minimum voltage in fence should be 4,0 kV (4000V) depending on the model of the energiser.
Testing the energiser Test your energiser with Olli Digitester or Supertester Disconnect the energiser from the fence and check the voltage between the buttons of the energiser Switch the energiser on and touch the earth button (Black) of the energiser marked with the earth probe on the tester. With the tester touch the Positive button (Red) marked with the pin on the tester.
Depending on the energiser the tester should show voltage 4000-10 000 V (Digitester: 1 kV = 1000 V).
Olli 1000 Energiser Tells you there is a problem;
The Power going to the fence
Checks the earthing
Checks the return power from the fence
There are 3 levels of checking – Happy – Be Careful – Sad • Happy – Do Nothing • Be careful - Check the fence there is a power loss • Sad - There is a real problem
A normal electric fence in winter
No Shock !
ATTENTION !
Snow/Ice insulates the ground and does not allow the electricity to go to the earth stake, so the animal does not get a shock !
Electric fence for all-year-round use
There are 2 options to build a winter fence: 1. “Double contact” fence • • •
Two lines one positive one negative Problem is to stop them touching each other Not recommended
2. Fence using winter tape or a “thick board” 100 mm tape •
