Voltage sag is considered as one of the most common power quality problems causing sensitive equipment to malfunction and many industrial process interruptions. Complains about the economic loss and equipment damage from industrial customers has stimulated the investigation on the voltage sag source location. As a result, many efforts have been made to know the location of voltage sags by utilizing various concepts. Generally, there are two broad categories of methods to locate voltage sags source, namely, single and multi-monitor based methods. Therefore, the purpose of this paper is to present a comprehensive review of articles that involves various methods to identify the location of voltage sag source. Accordingly, the concepts, advantages and disadvantages of these methods are discussed and tabulated for review. Although this paper does not exhibit a numerical performance comparison, most of the research publications under the subject of voltage sag source location methods have been sorted and appended for a rapid reference.
