A REVIEW ON MAGNETIZING INRUSH CURRENT. [PDF]
Magnetizinginrush current is a current which occurs in transformer during switchingon..The main objective is to examine the cause and effects of magnetizing inrush current on transformer. The paper also suggests measures to remedy dangers posed by magnetizing inrush current in transformers.

Inductance inrush current time–frequency analysis [PDF]
This study presents an application of the reassigned Gabor time–frequency transform to the inductance inrush current transient analysis. Measurement setup is constructed and the measurement methodology is presented to obtain fully controlled transformer inrush current measurements.

Pre-energize Analysis on 3 Phase Transformer by Considering Each Phase Flux
Inrush current is a transient phenomenon that occurs when a transformer is first energized to a voltage source at no-load conditions. It causes a very high inrush current.

In recent years, the zero-mode inrush current of high-impedance transformer with built-in high-voltage winding (T-Hin), which has large amplitude and decays slowly, causes the misoperation of zero-sequence overcurrent protection.

When the electromagnetic transients occur in a power transformer, an inrush current is generated in its winding. The inrush current not only affects the performance of the transformer windings, but also affects the lifetime of the transformer.

Power Transformer Modeling for Inrush Current Calculation [PDF]
In this thesis a general purpose transformer model for low and medium frequency transient studies is developed and verified. The inrush current phenomena during no-load energization of power transformer is analyzed with special attention.
