Lightning Protection Technique for Computer System

介绍了雷电等过电压侵入计算机（或电子设备）系统的途径，研究了如何防止由线路和地线进入的过电压。分析了两种接地系统及怎样正确选择接地系统。

The intrusion way of over-voltage like lightning into computer (electronic system) was intro- duced, and the protection methods against over-volt- age from circuits and ground were studied. Two ground- ed systems were analyzed and the correct way to select grounded system was presented.
