Abstract - In the View of sizing an electrical installation and the required equipment, as well as determining the means required for the protection of life and property, Problems that may occur at any point in the Power System.
There are two major problems that can occur in power system; these are open circuits fault and short circuits fault. Of the two, short circuit is the most dangerous because it can lead to very high fault currents and these currents can have very substantial effects such as electromechanical forces and thermal heating on equipment that may need replacement of equipment and may even cause fires and other similar ensuing effects in the power system
To prevent problems from short circuits, it is required to design electrical protection systems that will be able to detect abnormal fault currents that may occur and then take remedial action to isolate the faulty section of the system in as short a time as is consistent with the magnitude of the short circuit fault current level. This requires that the fault current be predicted for a fault in any particular location of the power system. This paper described the Simulation Model of Distribution System Based on the Short Circuit Analysis. This analysis is done by using ETAP Software (Electrical Transient Analyzer Program Software) and it is based on International Electrotechnical Commission (IEC) – 60909 Standards.
With the help of this Analysis, we will be able to do the Selection of Switchgear Equipment as Circuit Breaker, Fuses, Power Contactors, Over Load Relays and Appropriate Relay and do the Relay Setting if any as per project requirement
