Hi everybody,
I want to make a HV-wire on top of a fence. The HV is fed through the entire cable length. To find the location of the broken wire easily between two poles of the fence I want to divide that wire into may sections.
My idea: Connect a constant current source (4mA) to each section (between two poles) and measure the voltage drop in the controller at the load resistor having 500Ohms. As soon as one section is broken the voltage drop (normally 2V) reduces to zero and trigger the alarm circuit indicating the exact position of the damage.
Both circuits will have separate ground connections, the fence will have "earth" as ground.
Could that circuit work OK?
