我国电力系统常用的中性点接地方式有:中性点直接接地、中性点不接地、中性点经消弧线圈接地(谐振接地)、中性点经电阻接地这四种方式。电力系统接地运行方式涉及电网的安全运行、供电可靠性、用户用电安全等诸多重要问题。
The common grounding modes of neutral point in China's power system are: direct grounding of neutral point, non-grounding of neutral point, grounding of neutral point through arc suppression coil (resonance grounding), and grounding of neutral point through resistance. The grounding operation www.tangangfengtou.cnwww.tubuji.com.cnwww.tiemianji.cnwww.diandongmens.cn www.yazhujian.com.cnwww.caoxingtuogun.cnmode of power system involves many important issues such as safe operation of power grid, reliability of power supply, safety of user's power consumption, etc.
在专业技术方面涉及电力系统、过电压与绝缘配合、继电保护、通信与自控、电磁兼容、接地设计等诸多领域，是一个内容广泛的系统问题。
In terms of professional technology, it involves many fields such as power system, over-voltage and insulation coordination, relay protection, communication and control, electromagnetic compatibility, grounding design and so on. It is a wide-ranging system problem.
