摘要
对10kV中性点不接地系统的现场单相接地试验结果进行分析,给出了系统在发生不同性质单相接地故障时故障相电压的变化规律,为准确判断故障相提供了理论依据。
By analyzing the result of a single-phase grounding fault test on a lO kV isolated neutral system, the changing patterns of the faulty phase voltage caused by different-type single-phase grounding faults are studied, which provides theoretical foundation for identifying the faulty phase correctly.
