Abstract
In this study, samples from the site where there occurred unbalanced current when cable routing were analyzed, and the simulation program for electric power system analysis, PSCAD/EMTDC, was used to calculate the current unbalance on cable routing. Based on electromagnetic finite element analysis(FEA), electromagnetic parameters enabled the interlocking with COMSOL for the calculation of allowable current ampacity and magnetic filed distribution. This then led to modeling unbalanced current between common modes using the unbalanced current analysis program, thereby comparing and discussing the results from both. The analyzed model is a common mode 2 parallel circuit, which is a basic model for cable routing, and by arranging cables in various ways, the arrangement with the least current unbalance was suggested, which would, in the future, prevent earth faults and extend life for the whole cable.
