   Murray loop test employs the principle of wheatstone bridge for locating the fault. To perform this test, it is necessary to have a sound cable running alongside the faulty cable. One end of the faulted cable is connected through a pair of resistors to the voltage source. Also a null detector is connected. The other end of the cable is shorted.

5. Ground-penetrating radar - Wikipedia

   en.wikipedia.org/wiki/Ground-penetrating_radar

   Borehole radars utilizing GPR are used to map the structures from a borehole in underground mining applications. Modern directional borehole radar systems are able to produce three-dimensional images from measurements in a single borehole. [8] One of the other main applications for ground-penetrating radars is for locating underground utilities.
