Short circuit analysis is an essential tool for safe and reliable operation of industrial power systems. In this paper, a detailed fault analysis of the multi-bus industrial power network is presented according to the IEC 60909 standard and modeled in ETAP 19.0.1C. Symmetrical (three-phase) and unsymmetrical faults (line-to-ground (LG), line-to-line (LL), and double line-to-ground (LLG)) are studied. The system has several generators, transformers, transmission lines and loads operating at different voltage levels. The fault currents, peak currents and the breaking currents at the critical buses are evaluated to layout the system response in an abnormal condition. The results indicate that the three phase faults produce highest fault current but unsymmetrical faults are different in sequence impedance characteristics. The results of this research show the importance of impedance, earthing and system arrangement in fault study and can be used as a guide for protection system design and device select technique.
