Fault analysis studies are essential analytic tool for designing and planning of power systems. They are considered the most important and complicated matter in power engineering. Customarily, analyzing of power systems under fault conditions is restricted to using of Symmetrical Components method although there is another useful method such as Clarke Transformation. This research presents performing theoretical and simulation fault analysis studies for low voltage distribution system using both Symmetrical Components and modified Clarke Transformation methods, comparing between both techniques, and highlighting the interrelation between them. This research gives a general derivations of equivalent circuits for various operating conditions in power system based on modified Clarke Transformation. A comprehensive theoretical fault analysis for 3-PH, 3-PH-G, S-L-G, L-T-L, and D-L-G fault conditions in power distribution system have been implemented based on Symmetrical Components and modified Clarke Transformation. Moreover, simulation fault analysis studies using PSCAD/EMTDC Software are presented in this research for performing the fault conditions using both methods. The findings of this research show some advantages for using Clarke Transformation method in fault analysis compared to using Symmetrical Components. Analysis results show that Clarke Transformation provides easier solution and equivalent circuits for most of fault conditions. Furthermore, simulation results show that fault conditioning provided by Clarke Transformation is clearer and simpler than thus provided by Symmetrical Components.
