Good day every one, My name is Thebe and I like to play around with low voltage electronic devices, currently I have an electronic system that I am trying to build on 24 volts but the problem is that some of the wires in my circuit must run next to a very high voltage cable so I am concern about the electro-magnetic field from the high voltage cable that it might affect my system. I would therefore kindly like to propose for assistance from anyone with the knowledge about electro-magnetic field. Below is a brief explanation of my circuit: I first connect a negative terminal of a 24v battery with a wire to the negative connector of the my device and then connect the + terminal of the battery with a 100m long insulated wire and run it just next(5mm) to the 3kv overhead cable for a 50m distance and then allow the cable make a u-turn back and this time it is not running next to the 3kv cable but it is now running under the ground until it reaches the + connector of my electronic system. So what I am trying to find out is that is it possible for the magnetic field of the overhead cable to burn my wire or short circuit my system? Please take a look at the drawing from the link below before you answer me so that you can understand my question better. http://www.thebesonic.com/Magnetic fied.htm" Your help will be highly appreciated.
