智能电网（SG）的发展可能需要将众多消费电子设备和电器相互连接，并与外部世界连接。随着设备的互联程度越来越高，适当的安装实践在电磁兼容性（EMC）和电磁干扰（EMI）方面的重要性也越来越大。与EMI相关的最具破坏性的现象是雷击，雷击可导致建筑物上的高能浪涌和环波瞬变？s电源和通信布线及其接地系统；静电放电，这是一种环波瞬态形式，因湿度低而加剧；以及来自设备电源、荧光镇流器、焊工、开关、无线通信设备、调光器和其他来源的传导和辐射射频（RF）能量。

The development of the Smart Grid (SG) may entail the interconnection of numerous consumer electronic devices and appliances to each other and to the outside world. As devices become more interconnected the importance of proper installation practices with respect to electromagnetic compatibility (EMC) and electromagnetic interference (EMI) grows. The most destructive phenomena associated with EMI is lightning strikes, which can result in high energy surges and ring wave transients on a building?s power and communications wiring and its grounding system; electrostatic discharge, which is a form of ring wave transient that is exacerbated by low humidity; and conducted and radiated radio frequency (RF) energy from equipment power supplies, florescent ballasts, welders, switching, wireless communications devices, dimmers, and other sources.
