Electric power cables are considered as one of the essential elements in electric transmission and distribution systems. Any failure in these equipments directly reduces system reliability and increases maintenance costs. Consequently, the preventive maintenance techniques and also fault diagnosis methods are increasingly developed In this regard, frequency response analysis (ERA) can be taken to be account an appropriate method in order to diagnose any change which occurs in cables physical construction.
This contribution has concentrated on the application of frequency analysis measurements as a new kind of diagnostic lest to investigate its ability for diagnosing a few numbers of common faults which are occurred in power cables. Experimental measurements have been performed on a power cable using ERA analyzer instrument in two healthy and faulty situations. All intentional faults have been experimentally applied on geometry of cables and the ERA results have been measured and compared The obtained results are very interesting and applicable for maintenance aims to find the happened fault, quickly.
