10kV小电阻接地系统电流互感器配置和选择

Matching and Selecting CT for the 10kV System that the Neutral Point of Which is Grounded by Low Resistance

本文介绍广州地区10kV小电阻接地系统电流互感器配置和选择情况,并进行分析比较。根据中性点经小电阻接地系统不同于中性点直接接地系统和中性点不接地系统的特点,提出对中性点经小电阻接地系统电流互感器配置和选择意见。

In this paper, the author introduces the situation about matching and selecting CT for 10kV system that the neutral point of which has been grounded by low resistance in Guoangzhou City, and does the analysis & comparison. According to the difference of the systems that the neutral point of which would be grounded by low resistance, grounded directly or not grounded, the author presents the view about matching and selecting CT for 10kv system that the neutral point of which would be grounded by low resistance.
