Goran Petrovic, Tomislav Kilic, Stanko Milun

Abstract

The inrush currents generated during a energization of power transformer can reach very high values and may cause many problems in power system. In this paper method for controlled energization of power transformer based on measuring of remanent flux of magnetic core is presented. The remanent flux is measured and memorized at the last de-energization of transformer and then applied at next energization. Experimental results of inrush currents at controlled energization of transformer are presented.
