? Electric energy is one of the fundamental resources of modern industrial society. Electric power is available to the user instantly, at the correct voltage and frequency, and exactly in the amount that is needed. This remarkable performance is achieved through careful planning, design, installation and operation of a very complex network of generators, transformers, and transmission and distribution lines. We must examine all possible types of fault or abnormal conditions which may occur in the power system. The analysis of power systems under faulted condition provides information regarding circuit breaker selection, relay setting, and the stability of the systems operation. In this study, a balanced three phase fault current at a given bus of the system is calculated by using different methods. Especially emphasis on the MVA method and compared other conventional methods.
