Identifying Transformer Inrush Current Based on Artificial Neural Network
, 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.

Deep Underground Science and Engineering, Volume 5, Issue 2, Page 615-632, June 2026.This study investigates ground subsidence during tunnel excavation in karst areas, highlighting the combined effects of karst cave proximity, cave size, and soil spatial variability. Findings suggest that shorter cave distances and larger cave sizes increase subsidence variability, and a modified Peck formula is proposed for more accurate subsidence ...

High Voltage, Volume 11, Issue 3, Page 668-680, June 2026.ABSTRACT The breathing system of an oil‐immersed transformer is of vital importance for maintaining equilibrium between internal and external pressures, with any malfunction potentially disrupting the transformer's stable operation. This study develops a thermal–fluid–structure interaction (TFSI) model to simulate the breathing phenomenon in a 110 kV ...

Inrush Current Reduction of Three-Phase Transformers Using Optimal Energization Angle Control
IEEE AccessWhen a transformer is energized, the inrush current can reach several tens of times higher than the steady-state magnetizing current, which may cause maloperation of protective relays, voltage dips and deterioration of power quality.

Electronic suppression of transformer inrush currents
International Journal of Electrical Power & Energy Systems, 1988 Abstract A novel electronic technique for suppressing transformer inrush currents is outlined. The suppression concept is based on the generation of a time-expanding triggering signal controlling an electronic switch which is connected to the primary winding of the transformer.
