In this paper, the authors propose a new method for identification of magnetizing inrush current phenomena. In general, the identification is performed using the current waveform. However, saturation of current transformers makes it impossible to obtain such a waveform. Therefore, the authors introduce an identification method using the voltage waveform, in which the transformer saturation voltage does not occur. By applying Aitken's (2) process, it is shown that the new identification method gives accurate saturation start and end times.
