- Abstract:
- The first part of the paper is focussed on own direct measurements of human body resistancecapacitance, in indissoluble connection with two resistances: the leakage and respective, the discharge ones. There are presented methods, set-ups and argued explanations for the large dispersion of the obtained results. The human impedance (capacitance shunted by leakage resistance) was measured by performing the ratio between the well known ac voltage (as r.m.s. and frequency) and the established current. In order to determine the skin resistance between different parts of the human body (wrist, elbow, shoulder, ankle), there were performed both ac and dc measurements.
The second part aims to investigate the relationship between the real skin resistance (in the main, determined by volume resistivity, not just surface one) and the factual disturbing potential of the associated discharge in order to evaluate the impact of the series resistance in an ESD gun upon the susceptibility test results. - Keywords:
