Study of charge injection phenomenon at the metal/insulating liquid interfaces

Effect of electrodes material on transient currents in dielectric liquid

“…4a-c). In addition, results presented in [26] do not show proportionality between the electrical current and the DC field for the three structures. This means that another kind of charge carriers acts with the supposed initially existing ones.…”

“…The effect of the applied field on the current was already discussed for each interface separately [26]. Here, the principal observations are recalled, and some additional discussion will be attempted.…”

“…After using it to study technological problems [25], this work aims to implement the PDC technique for a purely scientific purpose, it is to demonstrate experimentally that electronic charges can be injected from the metal electrodes into the insulating liquid. In fact, based on already presented measurements of charging currents [26] (where it is showed that the metal/liquid contact effectively acts on the general performances of the insulation), this paper aims to explore according to a purely scientific approach of the obtained data. Before this, it is important to look over the problem of the EDL [21,27], which may affect the experiments.…”
