摘要：

Electric charges in liquids are at the basis of numerous applications and may drive industrial hazards. The Thermal Step Method is applied to liquid/solid interfaces to validate the use of thermal stimuli techniques for space charge measurements in dielectric liquids. Experimental results obtained for different electrical double layers are presented and discussed. They show that thermal convection has no significant contribution to the signal compared to the response of the charges from the solid/liquid interface. The measured signals are in accordance with the classical theory of thermal methods in solids and are consistent with the behavior expected from numerical simulations.
