Fault Analysis of Underground Cable System with Magnetic Shield Using Finite Element Analysis

CH.V.N.S.Pavan Pushya | Dr.A.Ratinam

Abstract: In order to overcome the difficulties and problems especially the faults in overhead transmission systems which acts as intermediate link between generation and load end can be analyzed easily. Whereas in present day underground cables have attained greater importance because of reduced losses in distribution systems compared to overhead transmission lines. But the major problem in identifying the type of fault in these cables are quite complex. So for analyzing these faults in cables, a theory has been proposed based on installation of shields called magnetic shields in underground cables for fault detection and its classification in reference to overhead transmission lines. A detailed simulation by MTALAB/Simulink has been discussed. Finite elemental analysis is applied to the magnetic shield to determine the stress and strain in the shields which will be varying under abnormal conditions. The intensity of these stress levels determines the range of fault current which can be further verified by using Genetic and Chaotic algorithms. `
