- 中文摘要: This paper provides a comparison of the safety criteria of two widely accepted standards, i.e., IEC 479-1 and IEEE Std 80. The two standards differ in their definition of the permissible body current and their definition of body resistance. Another difference is that the IEC 479-1 does not provide guidance on human feet/soil contact impedances. It tacitly assumes that these impedances can be computed by the designer. This paper includes a comprehensive study of permissible touch and step voltages under these two standards for a wide range of conditions which enables direct comparison of the two standards. It is shown that differences exist. These differences are quantified in this paper.
