励磁突流現象の飽和重複パターンによる特定

抄録

In this paper, the authors propose a new identification method of the magnetizing inrush current phenomena. In general, the saturations of cores are overlapping. Then, the inrush current waveforms become two equivalent single transformer inrush currents. Moreover, the two inrush currents have the same polarity and the phase of first current is lead to the second current about (2π/3). Therefore, the authors introduce the identification method using with saturation overlap pattern. In this method, since the exact saturation on/off time is unused, the voltage measurements are not needed.
