Calculation of Influence on Discharge Current Peaks for Human Air Discharges of Spark Lengths and Breakdown Potential Gradients using Simplified Equivalent Circuit based on IEC Standard

Abstract

The air discharge currents from two humans having different physique with charging voltages of ±4 kV and ±8 kV are measured and compared to reveal that the same relationship as our previously published result holds between the peaks, spark lengths and potential gradients. The relationship is quantitatively shown by analyzing a simplified equivalent circuit for human air discharge based on the IEC standard.
