Voltage compensation-type inrush current limiter for reducing power transformer inrush current
IET Electric Power Applications, 2012 When a transformer is initially energised, its iron core is driven into saturation, which will result in high-amplitude magnetising inrush current. For lessening this transient phenomenon, a voltage compensation-type inrush current limiter (VCT-ICL) is presented in this study.
