This paper describes a new methodology for the fault analysis of an n-conductor electrical system, in which the phase imbalances, neutral cables, groundings, and other inherent characteristics of distribution systems are considered. The proposed methodology, which is based on the current-injection method, allows faults to be represented in a simple way and may be used to analyze several fault types, including internal, series, and simultaneous faults. The results of several cases are presented to show the efficiency of the proposed method.
