摘要：在工程系统安装与调试中，有些地方有大功率设备的使用，可能存在比较严重的电场和磁场干扰，在电源和导线之间形成耦合的干扰是比较的，它们表现为电容性耦合电感性耦合、电磁场辐射3种形式，系统接地就是使系统建立与大地的连接，使设备能地抵抗这些干扰并正常工作。

Abstract:In the process of installation and debugging of engineering system,because of large power equipment used in some places,there may be serious electric and magnetic interference,the power and between the forming wires coupled interference is more prominent,they often performed in 3 forms:capacitively coupled inductive coupling,electromagnetic radiation,system grounding is to make the system establishment and the earth connection,so that the device can effectively resist these disturbances and normal work.
Keywords:Radio television;Grounding technology
一、接地的
接地技术最先主要应用于电力系统，后来接地技术才延伸应用到弱系统中，并在现代电子设备中越来越广泛的应用，说的“接地”就是指在系统与某个电位基准之间建立低电阻通路，相同接地点之间的连线被称为地线。-以上为可参考的写作提示
