Abstract- – Power system is prone to faults, because of disoperation of the system or by the natural disasters. This may be caused by damage to the components of power system leading to great tasked for their subrogation and cutting the power supply to customers. Different kinds of fault may occur in these lines. The over-current protection relay is the most extensively used component to safeguard power systems from the detrimental effects of faults. Wrong settings (pick-up value) in over-current relay parameters can lead to false tripping or even bypassing fault conditions which can lead to a catastrophe. Therefore, it is important to validate the settings of power protection equipment and to confirm its performance when subject to different fault conditions. The major purpose of this project is to simulate the operation of over-current relay and circuit breaker under different fault conditions in MATLAB, To analysis and studies the different faults and also declares the impact on distribution line.
