Research Abstract

In this study, we experimentally clarified the nature of the characteristics of the spark discharge that occurs when a grounded object moves toward a stationary charged object. The spark lengths, spark currents, and induced voltages in a probe were measured when a grounded metal spherical electrode approached a stationary charged metal spherical electrode connected to a capacitor for different moving speeds of the grounded metal spherical electrode. According to the result, the average gap length shortened with the moving speed of the spherical electrode. The average peak values of the spark current and the induced voltage were likely to increase with the moving speed of the spherical electrode. The average rise times of the spark current and the induced voltage were likely to reduce with the moving speed of the spherical electrode.
