I can feel what you feel when your BH was broken into with all fallen chicks esp the still alive ones which you don't know how to save them but Thanks GOD, all mine are still OK. Some of my friends have their BHs broken into esp. those 2S BH in town and those @ agriland. The 2S BH seem to get broken in so often like every few months once.
I will love to use TF electric 15KV neon transformer on the thieves to see them suffer and to pay for their sin. By the way, how is the circuit diagram cos I surely don't want myself to get the shock.
Neon transformers are very simple and properly used are not particularly dangerous to humans, just extremely uncomfortable.
First there are several types of neon transformers and in this case those made in hongkong are the best. They are the simplest and do not contain electronic boosters that will easily burn out. They are also sealed with tar and therefore weather proof but very heavy. Electronic neon trans are very light and compact.
Neon transformer is basically a step up transformer converting 240 volts ac to 15000v ac. The input is current limited so the output is also current limited. Only difference between a normal step up trans and the neon trans is that it is centre tapped to earth so either output wire gives 7500v to earth but 15000v between the output wires.
So touching one wire will give a 7500v shock and both wires will give 15000v ac.
The output wires must be connected using special high tension wires as in motor ignition spark plug wires. These are kept about 12 inches apart to prevent shorting. The live wires are of course uninsulated wires, I use stainless steel wires, similar to that used for fishing tackle.
Routing the live wire is as you prefer but these must be insulated from post and fittings. I use empty coke bottles as insulating posts. The steel support post goes inside the bottle and the live wire is looped round the outside of the bottle.
The earth of the transformer must go to a steel or copper earth pole embedded into the ground about 10 ft deep and about 30ft apart all around or you can run a separate earth wire together with the live wires.
If the earth is not embedded into the ground, anyone touching one live wire will only get a very mild shock. Touching both live wires will of course give a full 15kv shock.
Little neon lamps can be connected all along the fence to give some visual warning. ( same as those in test pens)
The electric fence must be placed in an area where it is not easily shorted out with the use of a chain or wire. That is why electric fences are primarily used for animals !
