This paper were carried to investigate the effect of self-impedance and mutual impedance in the estimation of the voltage sag in each node. The voltage sag estimation were carried on the TNB 132/11kV distribution network with a single-line-to-ground fault occur in the network. The result shows that when a high fault impedance occur, the impact of mutual impedance will be less. Impedance-based method have a reasonable accuracy in estimate the voltage sag value for each node in the network. Further work can be continue for fault distance estimation based on the accuracy of voltage sag estimation.
