Abstract

This paper presents an exposure assessment study for live-line workers exposed to transmission line power frequency electric and magnetic fields. A double circuit transmission line is selected. Practical exposure scenarios which represent actual working conditions for live-line workers have been identified. The charge simulation method has been adopted to compute the external electric field around the selected 132 kV transmission line. A method based on Ampere law has been chosen to compute the external magnetic field around the transmission line. Both methods are numerically solved using the EPRFs EMF Workstation software. A comparison between the values of external electric and magnetic fields, with the allowable exposure limits set by the international standards has been conducted. The paper concluded that the levels of workers exposures to extremely low frequency electric and magnetic fields are below the recommended international standards limits for the scenarios considered in this work

SEC 132 kV输电线路带电作业人员极低频电磁场暴露评价

本文介绍了输电线路工频电场和磁场对带电作业人员的暴露评价研究。选择双回路传输线。已经确定了代表现场工人实际工作条件的实际暴露情景。采用电荷模拟的方法，对选取的132 kV输电线路周围的外加电场进行了计算。采用基于安培定律的方法计算传输线周围的外磁场。采用EPRFs EMF Workstation软件对两种方法进行了数值求解。将外部电场和磁场值与国际标准规定的允许暴露限值进行了比较。该论文的结论是，工人暴露于极低频电场和磁场的水平低于本工作中考虑的情景所建议的国际标准限值
