A Specific Relationship between Breakdown Potential Gradients and Discharge Current Peaks for Air Discharges from Charged Human

Abstract

Measurements of discharge current waveforms are conducted for the air discharges from a charged human with voltages of ± 4 kV and ± 8 kV to estimate the spark lengths. The result shows that a specific relationship holds between breakdown potential gradients and discharge current peaks regardless of charging voltages, their polarities, approach speeds and climatic conditions.
