hi,


separate into two pieces on any point of the kilometer length of the wire?

ya.you are right.its need to detect the separate into two pieces wire on any point of the kilometer length by detecting the voltage on the wire.

I need to build an device to detect the separated wire (eg: TDR) . So i'm wondering which sensor or other component can be use and low cost.

Thanks
