Abstract

Abstract: The need for power is constantly rising, with the current economic growth. In the power distribution system, transmission lines are the most important part as they play an indispensable role in transferring power from the power plant to the load centres. Transmission lines are done to faults which are largely caused by dampness in the paper insulation, weakness of the cable, or defects in splices or other accessories. The presence of these faults cases the power transmission efficiency to become low, giving rise to a huge annual power loss, Finding and designing new methods to identify the type of defect and its location, is the key to increasing the reliability and optimal performance of the system. This paper reviews about various approaches used for determining the location of underground cable faults and determining the faults using thermal imaging.
