An important and essential diagnostic tool for insulation systems in condition monitoring is partial discharge (PD) measurement. Through PD measurement, the results may be used for insulation condition assessment. However, the modelling of PD is important because it is helpful in attaining a better understanding of PD phenomenon. The physical mechanisms and critical parameters influencing PD events...
Supercapacitors are components for energy storage, dedicated for applications where both energy and power density are needed. Even if their energy density is ten times lower than the energy density of batteries, supercapacitors offer new alternatives for applications where energy storage is needed. We have done an experimental bench and we have measured the voltage across a supercapacitor in a constant...
This paper deals with the fractional order modelling of the supercapacitor voltage response for a given current profile. The model is obtained using the porous electrode theory applied on the supercapacitor case. In order to simplify the complexity of the model, it is assumed that there is no diffusion process in the electrolyte. These assumption leads to neglect the supercapacitor self-discharge...
