  Today due to the increasing consumption of electrical energy and the use of non-linear loads that create transient regime states in distribution networks, analysis of power quality for energy sustainability in power networks has become more important. Transients are often created by energy injection through switching or lightning and make changes in voltage and nominal current. Sudden increase or decrease in voltage or current makes characteristics of the transient regime. This paper investigates and identifies capacitor bank switching, which is one of the causes of oscillatory transient regime states in distribution network, using wavelet transform. By identifying the switching current of capacitor bank and the internal fault current of the transformer to prevent the unnecessary outage of differential relay, it will propose a new smart method. The accurate performance of this method is shown by simulation in EMTP and MATLAB تفاصيل المقالة
