Novel method of charge mobility assignation in liquid dielectrics by streaming electrification Br

The mobility of charge carriers is the parameter used for describing conductivity caused by the electrification activity. It is studied for substances of various states of aggregation, in the range including gases, liquids and solid bodies, for conductors, semi-conductors and dielectrics. The knowledge of this value is of great significance for the research work on insulation liquids. Transformer insulation oils, where due to the range of interest this issue is especially significant, serve as a good example. The paper presents a new method of the research on the mobility of charge carriers in insulation liquids, based on the application of the streaming electrification measurements of such liquids.
