Homogeneous discharge is a hot topic with a lot of practical value in the field of plasma. With the change of gas condition (e.g. the gas pressure and composition etc.), a transition from partial discharge mode (or filamentary mode) to homogeneous discharge occurs. In this article, the surface charge behavior of the transition from filamentary mode to homogeneous mode was investigated. The dynamic...
In this paper, a measurement system of dynamic surface charge distribution based on Pockels effect was designed. Different polymer materials such as LDPE, PP, OPP, PET and PTFE were employed in the test. The surface charge distributions on dielectrics under needle-plate electrode have been measured within two cycles of sinusoidal voltage (50Hz, peak value 4kV). By analyzing the pattern and maximum...
Sato's equation has been employed to calculate the pulse current caused by dielectric barrier discharge (DBD). However, it was derived from the gas discharge in a gap between both metallic electrodes. Hence, due to the existence of surface charges, the applicability of Sato's equation to DBD needs to be clarified. In this paper, the models about gas discharge in a gap between electrodes, one electrode...
