Abstract :
The purpose of this study is to clarify the factor of the appearance of Swarming Pulsive Microdischarges (SPMD). For this end, the surface potential distribution of dielectric materials after partial discharge (PD) exposure and its time dependence were measured in connection with surface roughness
