Well, I am not familiar with this detection or application, but you might be able to search for some information by googling TDR.
TDR stand for Time Domain Reflectometry, and the device to perform this task is also call TDR - Time Domain Reflectometer.
Good luck

If you just want to detect wire cut, just create a circuit like the picture below and check the output (HIGH or LOW)
