Answer #1

Answer : Locating the faults at a distance D=10 m. by using time domain reflector (TDR) ,using the formula D =Vp(T/2)

Where Vp is velocity propagation ,T = transit time from the monitoring point to the mismatch in seconds.

This is a straightforward calculation to make and is normally made within the time domain reflectometer, giving the user a good indication of where the fault may be located.

The main issue is the propagation velocity within the cable. This can be determined by testing a known length of the cable under test and leaving the remote end open.
