摘要
针对目前小电流接地系统的接地选线装置现场选线的准确性差、投入率不高的问题,根据系统的特点对问题进行了工程应用上的分析,经过对小电流接地系统的理论分析、选线设备原理、采样误差等方面对问题进行剖析,提出了减小综合测量误差,提高选线准确性、可靠性的措施。
As to on-site fault line selection of power system with indirectly grounded neutral, its accuracy and application results are not satisfactory. Aiming at that problem and based on the characteristics of the system, the paper analyses the problems from the perspective of engineering application, and puts forward measures with which the errors can be reduced, and correctness and reliability of fault line selection can be improved.
