Abstract Constant switching occur in transformers due to imbalances between power generation and load served. This fact generates a magnetizing transient current on the transformer called “inrush current” resulting in numerous problems. Thus, this paper addresses the basictheoretical study of inrush currents and shows its influence in the transformer protection systems. Moreover, it also presented a list of major works that address this transient phenomenon.
