Fault Location on Rural Underground Power Lines

New types of direct burial cable, associated devices, and methods, coupled with ecological pressures, have resulted in phenomenal growth of underground power distribution. Applications are going far beyond previous industrial and residential development use. Often loop or alternate feeds are not available, particularly in rural radial systems. Rapid service restoration may depend upon cable tracing and fault location. The proliferation of under-ground utilities with increasing possibility of excavation damage makes on-site route tracing and depth finding highly desirable. The ready availability of suitable tracing and fault locating equipment in the hands of trained personnel becomes of greater importance as installations multiply.
