An Identification Method of Magnetizing Inrush Current Phenomena by Voltage Waveform

Abstract

In this paper, the authors propose a new identification method of the magnetizing inrush current phenomena. In general, the identification is done using with current waveform. However, the saturation of current transformer can't give waveform. Therefore, the authors introduce the identification method using with voltage waveform, in which the saturation of voltage transformer doesn't happen. And then, applying the Aitken's Δ²-process, it is showed that the new identification method gives the exact saturation on/off time.
