摘要

本次调查考虑了三个国家和国际接地系统标准，即IEEE 80, BS 7354和EA-TS 41-24，对接地系统设计和安全的建议和程序。在本文中，我们提出了考虑网格大小、网格密度、大地电阻率和体电阻的不同建议的比较参数评价结果。得到了安全极限曲线，根据不同的标准对各种设计进行了分类。通过对这些生成的安全极限曲线的研究，不仅可以明确哪些电网特性安全条件适合安装，还可以制定一个考虑标准中考虑的所有条件的最佳设计程序

Parametric Analysis of Safety Limit-Curves in Earthing Systems and Comparison of International Standard Recommendations

Recommendations and procedures for the design and safety of earthing systems from three national and international standards for earthing systems, namely IEEE 80, BS 7354 and EA-TS 41-24 have been considered in this investigation. In this paper, we present the results of a comparative parametric evaluation of the different recommendations taking into account the grid size, mesh density, earth resistivity and body resistance. Safety limit-curves were obtained, which classified the various designs according to the different standards. Through investigation of the so-generated safety limit-curves, it is possible not only to clarify for what grid characteristics safe conditions are obtained for the installation but also to develop an optimum design procedure that accounts for all conditions considered within the standards
