An underground cable fault is the name given to a disruption or rupture in an underground cable. Cable issues can be caused by a variety of factors, including as standard wear and tear, damage from excavation, dampness, temperature fluctuations, or other outside factors. Tracking down and resolving cable issues can be challenging because specific equipment and expertise are needed. It takes longer to test the cable for flaws in order to find a fault in it. When an underground cable malfunctions, it can be challenging to pinpoint the exact position of the problem so that the line can be fixed. The goal of the project work is to locate, in kilometres, the location of a defect in subterranean cable lines starting at the base station.
