Faults in the power system are major cause of voltage sag. Voltage sag in the power system due to fault can be symmetrical or unsymmetrical. For sensitive loads it is necessary to estimate how many times in year the voltage at their terminal will experience sag to avoid tripping of operation. Several stochastic methods for estimation of number of sags are developed in recent years. In different methods of sag prediction there is need to do lengthy programming or calculations. Here PSCAD/EMTDC software package is used to estimate number of sag with uniform distribution of faults along the lines.
