This experiment focuses on fault analysis in power systems using simulation tools like MATLAB, PsCAD, ETAP, EMTP, PSS etc. It covers the importance of relay setting and impedance calculation. The experiment analyzes fault currents for different fault points in the network. The network diagram is provided with suitable data for generator and transformer. The per unit impedance of the network components is calculated and the impedance diagram is drawn. The experiment also covers the calculation of fault current for different fault points in the network.
