You can find the faulted location with the help of multimeter.

Measure the capacitance at both the ends,between faulted
phase with respect to earth.
For one end if it is C1 and for other end it is C2. And
total length of cable is L and Capacitance is C.

Then by using the below formula, you can find the faulted
location

LC=L1c1+L2c2
