Charging and reversal currents in hydraulic liquids

Abstract

This paper shows the dependence of the electrophysical characteristics for some hydraulic liquids on the level of purification. Commercial Hydraulic Liquids such as JI3-MΓ2, PMII and MΓE-10A (Russian designation) both in original state and after purification through the glass filters were studied by the conductometric measurements. Such important parameters as value of the volume resistivity ρ and mobility of charge carriers μ were calculated or measured.
