| Abstract: | Objective To investigate the process and mechanism of insulator surface charge accumulation under impulse voltage, a dynamic equation was established for describing the relationship between surface charge density and applied voltage. Results The established equation is more generalized in comparison with that given by other previous investigators. Constants A, B for typical electrodes used in the present equation are specified. The process and mechanism of surface charge accumulation under impulse voltage are studied and the factors that influence surface charge accumulation discussed. Conclusion The present theoretical studies help to explain why surface charging can be accomplished instantly under impulse voltage, and determine the factors influencing surface charge accumulation. The findings confirmed some surface charging phenomena observed in GIS by some previous investigators. |
