Ferroresonance is a non-linear phenomenon and very dynamic in the power quality problems. This phenomenon should be carefully analyzed so that preventive measures could be taken before its appearance and prevent injury and damage to electrical power appliances. Ferroresonance is seen more in the middle-voltage networks with supplying unloaded or slightly loaded transformers by cables. The mater...

This paper introduces the latest research achievements on hysteresis modeling for power magnetic devices based circuit method. First, model considering behavior is derived. Next, this developed to reluctance network model, analyze more complicated such as an electric motor. Furthermore, improved take dynamic characteristics including skin effect into account. Finally, prediction method of deter...

Adsorption of gases in porous adsorbents such as coal and shale generally exhibits the phenomenon hysteresis. Most previous studies on desorption hysteresis were conducted via experimental tests. However, few theoretical models that represent adsorption–desorption sorbents are available. To address this issue, work develops a new model for describing adsorption isotherms with Particularly, ener...
