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: 10.1016/j.jsv.2018.07.037
Abstract: Abstract The sub-harmonic resonance phenomenon exists in multistage gear transmission system. Collision motion leads the sub-harmonic resonance instability, which brings harm to system stability. So investigating instability conditions of sub-harmonic resonance and effects of fault… read more here.
