Streaming electrification measurements in swinging cylinder system

The paper presents the results of streaming electrification measurements realized in a swinging cylinder system. Classical systems for the electrostatic charging tendency evaluation are presented along with their advantages and disadvantages. The paper presents briefly the construction of the proposed system. It allows for continuous measurement of electrification phenomena. Some examples are also presented that show the current responses for inner cylinder swinging. As a result, the analysis found that the electrification process is highly nonlinear. The spectrum response in the frequency domain contains a significant amount of harmonics.
