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.

Solid-State Inrush Current Limiter Controller Based on Inrush Prediction for Large Transformers
CoRR, 2020 Inrush current problems of the industrial transformers are occasionally more serious than the utility transformers. A new Solid-State Inrush Current Limiter (SSICL) is proposed for medium voltage power transformers. The SSICL consists of three similar sets.

Identifying Transformer Inrush Current Based on Artificial Neural Network [PDF]
, 2011 In this paper, lots of digital simulations of transformer magnetizing inrush current and fault current have been done through Matlab software. A neural network method used to identify magnetizing inrush current has been proposed and established.
