在GB-17626中,对雷击浪涌、电快速瞬变脉冲群等电磁抗扰度的测量都做了明确的规定.但是,这些测试中的传输线上往往存在着高频信号引起的电磁场噪声,严重地影响到了标准测试的准确性.借助CST MWS软件对相应的机理模型进行电磁场场强、远场辐射等的计算机仿真.帮助工程测试人员理解电磁干扰的实际存在,以提出解决应对的方法.

Nowadays, principles and standards for surge immunity and EFT test are set according to the EMC standards test such as GB17626. It also presents radiated interference of the high-frequency cable. Seriously radiated noise may affect the accuracy of the standard test. This paper tries to simulate electromagnetic field by CST MWS software. Engineers will understand radiated EMI noise analysis and suppression with the simulation result.
