DOI: 10.1016/j.asej.2019.04.002
Abstract: Abstract When a large power transformer is energized, a high magnitude inrush current may result in harmonic resonance overvoltage (HRO), if the system has resonance phenomenon. Such overvoltages may cause large stresses on the system.… read more here.

DOI: 10.1063/5.0195056
Abstract: Scale-invariant breathing oscillations are observed in similar magnetized discharges at different spatiotemporal scales via fully kinetic particle-in-cell simulations. With an increase in the similarity invariant B/p, i.e., the ratio of magnetic field to pressure, breathing… read more here.

DOI: 10.1109/access.2024.3385771
Abstract: Inrush current is high-magnitude current drawn by power transformers upon energization. The severity of inrush current depends on factors such as the transformer’s residual flux and the voltage phase angle at the energization instant. This… read more here.

DOI: 10.1109/tpwrd.2021.3054599
Abstract: The integration of overhead lines in future MTDC grids leads to a higher fault rate compared to cables. Most of the faults are considered to be non-permanent, so that the line can be reconnected after… read more here.
