摘要
为保证用电设备的供电可靠性,某工程低压配电系统的接地型式设计采用引出中性线的IT系统(即IT_N系统),并就此介绍IT_N系统的工程设计应用,特别是IT_N系统在线绝缘监测、故障定位技术的分析和应用。
In order to ensure the reliability of power supply for electrical equipment,the IT_N system that the IT system with neutral lead-out line,which is adopted in the grounding design of a low-voltage distribution system of a project.The engineering design and application of IT_N system,especially the analysis and application of on-line insulation monitoring and fault location technology of IT_N system are introduced.
