摘要
本文记述了一起罕见的,因接地不当形成地回路引起电磁干扰(EMI)的案例。详细介绍了这一奇怪现象和控制EMI的全过程。通过深入调查研究,分析了引起EMI的原因和控制措施;在总结经验的基础上阐述了在电缆敷设和接地设计时注意控制地回路的意义。
An Unwonted EMI Caused by Improper Grounding is described in this paper.Its phenomenon is recorded.Analyzing and con- trolling procedures are illuminated in step by step.From this EMI accident we have had a lesson,and realize the relationship between EMI and grounding loop,and pay more attenuation on cabling and grounding design in order to control the grounding loop area as small as possible.
