Grounding of Electrical System

电系统的放在地面上
大体上，大多数的电系统一定被置于地面。放在地面上的目的将限制由闪电，瞬间的巨涌和的意外接触较高的电压所引起的电压的大小。系统理由一定被安排提供一条最小阻抗的路径在发生。 涌流不应该在正常的操作期间流过放在地面上领导者。
直接-现在的系统 geerally 在补给车站对系统被连接放在地面上领导者,和不在个别的服务。交流电系统，另一方面，一定在每个个别的服务主要分离的补给边上被置于地面。对于关于位置和放在地面上的方法的特定资讯,提及 NEC 文章 250.
电力系统基地
一般来说！大多的电力系统必须是要接地好的。这样做的目的是限制由于闪电引起的电压！
