### Abstract

Voltage sag can cause hours of downtime, substantial loss of product and also can attribute to malfunctions, instabilities and shorter lifetime of the load. Accurate voltage sag source location can help to minimize the loss and problems caused by voltage sag in a power distribution system. This paper presents a development of a current component index algorithm to locate the source of voltage sag in a power distribution system. The product of the RMS current and the power factor angle at the monitoring point is employed for the sag source location. A graph of this product against time is plotted. The voltage sag source location is determined by examining the magnitude of the current component index at the beginning of the sag. The prototype of the method is also described in the paper. The proposed method has been verified by simulations and the results are proven to be in agreement when compared with the slope of the line fitting parameters of current and voltage method. This paper only focuses on a single source implementation.
