| Summary: | Inrush currents in transformers, which are resulted from system transient, are difficult to observe and analyze. Measurements of this inrush current offer important data for power system operation and protection. This paper proposes a simple method to simulate the calculation of magnetizing inrush current. The proposed method formulates a simplified model to present the inrush current under different loading conditions and switching angle. A program was developed using MATLAB 6.0 to perform the calculation of the magnetizing inrush current and to provide the simulation for the proposed method. Results obtained for the simulation shows that the developed method can provide faster calculation of magnetizing inrush current |
