IEC标准试验平台上辐射场分布规律研究

A Study of the Distributing Regularity of Radiated Fields on the IEC Test Platform

摘要: 国际标准IEC61000-4-2中对间接静电放电（Electrostatic Discharge, ESD）产生的辐射场没有进行描述.针对于此，笔者对IEC标准试验平台上辐射场分布规律进行了研究.实验得出： IEC标准试验平台上电场强度和磁场强度随测试距离的变化趋势不同；试验平台上电场强度和磁场强度在近场变化剧烈，在远场变化缓慢.

Abstract: The radiated field values are not specified in the ESD standard (IEC 61000-4-2) According to IEC61000-4-2 standard specification, the radiated fields on the IEC test platform were analyzed. The experimental results show that on the test platform: 1) the strength of the E-fields and H-fields varies with the change in distance; 2) the strength of the E-fields and H-fields varies greatly in close proximity to the discharge point, but varies slightly at the far distance.
