Electric Fence Specs

[Just Gone]

The developer is not keen on building another structure to facilitate this.
In your opinion, putting HT thru the cables for 500 m would work ? This is honestly the only solution I can come up with provided it is feasible ito. voltages.

500m is a long way for HT cable out and return - there is a lot to consider if doing this:
Type of energizers
Total meterage of live wire, including fence live wire and HT live wire
Thickness of live wire on the fence and HT cable
Type of wire ie braided, galvanized, stainless, High tensile
Zoned or not zoned

A building would still be cheaper than the cabling and what goes with the distance ........ and can be broken down easily afterwards.


How are you involved with the developer ? Are you the installer ?

I am not the installer............................Involved with the Home Owners Ass. wanting the issue to be resolved with the least amount of hassle.

Unfortunately there is no quick fix, as you can see from my previous posting.
Surely the developer is going to be running electricity to some areas, in which case this could solve your problem ?

I have a client in the Isando area that has a similar problem to yours. They have purchased 4 big deep cycle batteries and change them everyday. They then take the ones they have taken off to recharge. You do have to rely on a guard changing the battery tho, but at least he visits the energizers. You might want to consider this as a short term solution until permanent power is supplied.

Rather have a longer supply cable to the energiser, and keep the solar panels at the guard house. The wiring would be cheaper, because the system voltage is much lower than with the HT side. Depending on the current, there will be a voltage drop, but if you split and keep some lower capacity the batteries inside the energiser charged from the panels and the batteries in the guard house, then the wire size may be less of an issue.

With out further in depth information on the system, it is extremely difficult to provide any type of solution.

Then u need to send battery power to the energizers 500m away instead of HT power - voltage drop would be too great!

If that is a concern, then use an invertor to bring it to 220V AC, and it does not even have to be a sine wane, and on the other side you have a transformer bringing it down to DC. Far simpler solution. This solution has been around for years. Its the same solution in driving heavy loads on farms. In that case they increase the voltage to 11KV, and on the other side they drop it to 400V and drive up to 100Kwatt pumps. of course the transformers are suitably rated for that.

Or use 24V at the input and use a DC to DC convertor at the receiving end to give you 12V.

Have a look at a number of invertors here

What is the power we are talking about here? 300W, 600W, 1Kwatt?

[Just Gone]

I hear you but then u might as well just do away with the solar panels and just draw power from a 220v output without any converting and send that 500 m to the energizers.

True

By the addition of a simple bridge rectifier, performs the task quite remarkably.

I am not sure what the required input current is for these specific energizers is but I would think that 300 w @ 230 ac would be sufficient.
