In this paper, the authors propose an improved identification method of the magnetizing inrush current phenomena. To improve the estimation of the saturation on/off time, the Aitken's Δ2-process is adopted. And a new index δI, which is a variation current, is introduced. The merits of Aitken's Δ2-process are the simple algorithm and the high precision to oscillation noise. Then, the proposed method is adapted to a measured data, in which the oscillation noise is caused. The proposed method gives a high precision in these cases.
